[0001] This application claims priority from the Chinese patent application No. CN202411254321.4 filed on September 6, 2024, and entitled "A communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, and in particular, to a communication method and related apparatus. BACKGROUND

[0003] Wireless communication can be transmission communication between two or more communication devices without propagation through a conductor or cable. Generally, the two or more communication devices include a network device and a terminal device, or the two or more communication devices include different terminal devices.

[0004] Currently, in the communication process of different communication devices, a data sender can send data through a data channel, and correspondingly, a data receiver can receive data through the data channel to implement a data transmission process.

[0005] However, in the above data transmission process, how to improve the data transmission performance is a technical problem to be solved. SUMMARY

[0006] The present application provides a communication method and related apparatus for improving data transmission performance.

[0007] The first aspect of the present application provides a communication method, which is applied to a first communication apparatus, such as being executed by the first communication apparatus. The first communication apparatus can be a communication device (such as a terminal device or a network device), or the first communication apparatus can be a part of the communication device (for example, a circuit or a chip responsible for communication function (such as a Modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core) and the like), or the first communication apparatus can also be a logic module or software capable of realizing all or part of the communication device function. In the method, the first communication apparatus receives first configuration information, the first configuration information is used to configure a first resource of a first data channel; the first communication apparatus receives second configuration information, the second configuration information is used to configure a second resource; and the first communication apparatus sends or receives the first data channel on a third resource, wherein the third resource is included in the first resource, and the third resource does not include the second resource.

[0008] Based on the above scheme, the first configuration information received by the first communication device is used to configure the first resource of the first data channel, and the second configuration information received by the first communication device is used to configure the second resource; thereafter, the first communication device transmits or receives the first data channel on the third resource in the first resource, and the third resource does not include the second resource. In this way, the first communication device can implement transmission of the data channel on the third resource in the first resource except for the specified second resource, and can avoid or reduce the mutual influence and / or mutual interference between the transmission of the data channel and the transmission of other signals on the second resource, so as to improve the data transmission performance.

[0009] Optionally, the third resource is included in the first resource, which can be understood as that the third resource is a resource in the first resource, or the third resource is a subset of the first resource, or the one or more resource units included in the third resource are located in the first resource.

[0010] Optionally, the third resource does not include the second resource, which can be understood as that among the one or more resource units included in the third resource, there is at least one resource unit different from the one or more resource units included in the second resource; or the one or more resource units included in the third resource are different from the one or more resource units included in the second resource; or the resources in the third resource do not include the resources in the second resource.

[0011] It should be noted that the first communication device transmits or receives the first data channel on the third resource, which can be understood as that the first communication device receives data and / or signals of the first data channel on the third resource, or the first communication device transmits data and / or signals of the first data channel on the third resource.

[0012] As an example, taking the process of receiving the first data channel by the first communication device as an example. In the process, the first communication device can determine the second resource (i.e. the time-frequency resource on which data is not mapped) according to the second configuration information, and when the first communication device receives data on the first data channel, the first communication device can receive data on the third resource which does not include the second resource; in other words, the transmitting end can perform rate matching on data based on the second resource, i.e. the transmitting end can not transmit data on the second resource, and correspondingly, the first communication device can not receive data on the second resource.

[0013] As another example, taking the process of transmitting the first data channel by the first communication apparatus as an example. In the process, the first communication apparatus can determine the second resource (i.e., the time-frequency resource on which data is not mapped) according to the second configuration information, and when the first communication apparatus transmits data in the first data channel, the first communication apparatus can transmit data on the third resource excluding the second resource; in other words, the first communication apparatus can rate-match data based on the second resource, i.e., the first communication apparatus can not transmit data on the second resource, and correspondingly, the receiving end can not receive data on the second resource.

[0014] From the above process, it can be known that for the transceiver, the second resource can be a time-frequency resource on which data is not mapped.

[0015] For example, for the transmitting end, the transmitting end does not map data on the second resource (or determines not to map data on the second resource) through rate matching.

[0016] For example, for the transmitting end, the transmitting end can puncture (or delete, ignore, etc.) the bits carried by the second resource after mapping data on the first resource.

[0017] For example, for the receiving end, the receiving end can receive data on the third resource excluding the second resource.

[0018] For example, for the receiving end, the receiving end ignores (or skips) one or more resource units in the first resource that overlap with the second resource in the process of receiving data on the first resource.

[0019] Optionally, in the above process, the communication apparatus that communicates with the first communication apparatus on the first data channel can be a communication apparatus (e.g., the second communication apparatus) that transmits the first configuration information to the first communication apparatus, or can be another communication apparatus, which is not limited here.

[0020] In a possible implementation of the first aspect, the second resource is a control channel element (CCE) resource and / or a control channel demodulation reference signal (DMRS) resource.

[0021] Based on the above scheme, the third resource of the first data channel transmitted by the first communication apparatus does not include the CCE resource and / or the DMRS resource on the control channel. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource (i.e., the control channel resource) can be avoided or reduced.

[0022] Optionally, in the control channel, the second resource is a first part of resources in the control channel, the first part of resources being one or more CCE resources, or the first part of resources being one or more DMRS resources in the control channel, or the first part of resources being one or more CCE resources and one or more DMRS resources in the control channel. In the above scheme, the third resource of the first data channel transmitted by the first communication device does not include the first part of resources of the control channel, i.e., the first data channel transmitted by the first communication device can avoid the first part of resources of the control channel. In this way, while avoiding or reducing the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource, the data transmission can also be performed as much as possible by using the resources of the control channel, so as to improve the resource utilization and the spectrum efficiency.

[0023] Optionally, in the control channel, the second resource is a first part of resources in the control channel, the first part of resources being one or more CCE resources, or the first part of resources being one or more DMRS resources in the control channel, or the first part of resources being one or more CCE resources and one or more DMRS resources in the control channel. In the above scheme, the third resource of the first data channel transmitted by the first communication device does not include the first part of resources of the control channel, i.e., the first data channel transmitted by the first communication device can avoid the first part of resources of the control channel. In this way, while avoiding or reducing the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource, the data transmission can also be performed as much as possible by using the resources of the control channel, so as to improve the resource utilization and the spectrum efficiency.

[0024] In a possible implementation of the first aspect, the method further includes: receiving, by the first communication device, third configuration information, the third configuration information being used to indicate at least one of resource pattern information, code division multiplexing group information, and sequence information of the DMRS of the first data channel.

[0025] Based on the above scheme, the first communication device can further receive third configuration information, so that the first communication device can determine at least one of resource pattern information, code division multiplexing group information, and sequence information of the DMRS of the first data channel through the third configuration information, so as to receive the DMRS on the first data channel based on the at least one and demodulate / parse the data carried on the first data channel based on the received DMRS.

[0026] In a possible implementation form of the first aspect, the method further includes: receiving, by the first communication device, fourth configuration information, the fourth configuration information being used to indicate that a transport block size (TBS) corresponding to the first data channel is determined based on the third resource.

[0027] Based on the above scheme, the first communication device can further receive fourth configuration information, so that the first communication device can determine, through the fourth configuration information, that the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, so as to enable the first communication device to implement the reception or transmission of the first data channel based on the TBS associated with the third resource, improve the accuracy of TBS calculation, and further improve the transmission performance of the first data channel.

[0028] The second aspect of the present application provides a communication method, which is applied to a second communication device, such as being executed by the second communication device. The second communication device can be a communication device (such as a terminal device or a network device), or the second communication device can be a part of the communication device (such as a circuit or a chip responsible for communication function (such as a Modem chip, also known as a baseband chip, or a SoC chip or a SIP chip containing a modem core, etc.), or the second communication device can also be a logic module or software capable of implementing all or part of the functions of the communication device. In the method, the second communication device transmits first configuration information, the first configuration information being used to configure a first resource of a first data channel; the second communication device transmits second configuration information, the second configuration information being used to configure a second resource; wherein the first data channel is carried on a third resource, the third resource being included in the first resource, and the third resource excluding the second resource.

[0029] Based on the above scheme, the first configuration information transmitted by the second communication device to the first communication device is used to configure the first resource of the first data channel, and the second configuration information received by the first communication device is used to configure the second resource; thereafter, the first communication device transmits or receives the first data channel on the third resource in the first resource, the third resource excluding the second resource. In this way, the first communication device can implement the transmission of the data channel on the third resource in the first resource excluding the specified second resource, and can avoid or reduce the mutual influence and / or mutual interference between the transmission of the data channel and the transmission of other signals on the second resource, so as to improve the data transmission performance.

[0030] In a possible implementation form of the second aspect, the second resource is a CCE resource, and / or a control channel DMRS resource.

[0031] Based on the above scheme, the third resource of the first data channel transmitted by the first communication device does not include the CCE resource and / or the DMRS resource on the control channel. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource (i.e., the control channel resource) can be avoided or reduced.

[0032] Optionally, in the control channel, the second resource is a first part of resources in the control channel, the first part of resources is one or more CCE resources, or the first part of resources is one or more DMRS resources in the control channel, or the first part of resources is one or more CCE resources and one or more DMRS resources in the control channel. The control channel can further include a second part of resources, and the second resource does not include the second part of resources. In other words, in the above scheme, the third resource of the first data channel transmitted by the first communication device does not include the first part of resources of the control channel and includes part or all of the second part of resources of the control channel, i.e., the first data channel transmitted by the first communication device can avoid the first part of resources of the control channel, but cannot avoid the second part of resources of the control channel. In this way, while the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource can be avoided or reduced, data transmission using the resources of the control channel as much as possible can also be achieved to improve resource utilization and spectral efficiency.

[0033] In a possible implementation of the second aspect, the method further includes: the second communication device sending third configuration information, the third configuration information being used to indicate at least one of resource pattern information, code division multiplexing group information, and sequence information of the DMRS of the first data channel.

[0034] Based on the above scheme, the second communication device can further send third configuration information to the first communication device, so that the first communication device can determine at least one of resource pattern information, code division multiplexing group information, and sequence information of the DMRS of the first data channel through the third configuration information, so as to facilitate the first communication device to receive the DMRS on the first data channel based on the at least one and demodulate / parse the data carried on the first data channel based on the received DMRS.

[0035] In a possible implementation of the second aspect, the method further includes: the second communication device sending fourth configuration information, the fourth configuration information being used to indicate that the TBS corresponding to the first data channel is determined based on the third resource.

[0036] Based on the above scheme, the second communication device can further send fourth configuration information to the first communication device, so that the first communication device can determine that the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource through the fourth configuration information, so that the first communication device can implement the reception or transmission of the first data channel based on the TBS associated with the third resource, can improve the accuracy of TBS calculation, and can further improve the transmission performance of the first data channel.

[0037] In a possible implementation form of the first aspect or the second aspect, the second configuration information includes at least one of the following:

[0042] In a possible implementation form of the first aspect or the second aspect, the first information includes at least one of the following:

[0050] In a possible implementation of the first aspect or the second aspect, the fifth indication information includes at least one of the following:

[0051] a bit map corresponding to the CCE resources contained in the second resource;

[0052] a starting CCE index and / or a CCE number of the CCE resources contained in the second resource;

[0053] a bit map corresponding to a CCE group to which the CCE resources contained in the second resource belong; or

[0054] a starting CCE group index and / or a CCE group number of the CCE group to which the CCE resources contained in the second resource belong.

[0055] Based on the above scheme, the fifth indication information used for indicating the resource positions of the CCE resources contained in the second resource can include the at least one above, so as to improve the flexibility of the scheme implementation.

[0056] In a possible implementation of the first aspect or the second aspect, the second information includes at least one of the following:

[0057] seventh indication information, used for configuring a resource pattern of a ZP CSI-RS resource or a resource pattern of the DMRS resource contained in the second resource, the resource pattern of the ZP CSI-RS resource being the same as the resource pattern of the DMRS resource of the control channel;

[0058] eighth indication information, used for configuring a time domain position of the DMRS resource contained in the second resource; or

[0060] Based on the above scheme, the second information used for determining the DMRS resource contained in the second resource can include the at least one above, so as to improve the flexibility of the scheme implementation.

[0061] In a possible implementation of the first aspect or the second aspect, the eighth indication information is used for indicating any of the following:

[0062] a first bitmap used to determine a symbol position of the second resource;

[0063] at least one of a starting time unit position, a time unit quantity, a time domain density of the second resource;

[0064] a second bitmap used to indicate an association between a symbol position of the second resource and one or more candidate symbol positions; or

[0066] Based on the above scheme, the eighth indication information used to indicate the time domain position of the DMRS resource contained in the second resource can include the at least one above, so as to improve the flexibility of the scheme implementation.

[0067] In a possible implementation form of the first aspect or the second aspect, the ninth indication information is used to indicate any one of the following:

[0071] a fourth index corresponding to a frequency domain unit quantity of the second resource, the fourth index used to indicate one of one or more frequency domain unit quantities.

[0072] Based on the above scheme, the ninth indication information used to indicate the frequency domain position of the DMRS resource contained in the second resource can include the at least one above, so as to improve the flexibility of the scheme implementation.

[0073] In a possible implementation form of the first aspect or the second aspect, a carrier on which the first data channel is located is used to determine at least one of resource pattern information, code division multiplexing group information, sequence information of a DMRS of the first data channel.

[0074] Based on the above scheme, the DMRS of the first data channel can be used to demodulate / parse the data carried by the first data channel, wherein the carrier where the first data channel is located can be used to determine at least one of the resource pattern information, the code division multiplexing group information, and the sequence information of the DMRS of the first data channel. In this way, different carriers can have different DMRS configurations. Therefore, the first communication device can implement the reception or transmission of the DMRS based on the DMRS configuration corresponding to the carrier where the data channel is located, so as to improve the reception / parse success rate of the DMRS by the receiving side of the DMRS, and further improve the data reception performance.

[0075] Optionally, the third configuration information and the carrier where the first data channel is located described in the foregoing can be used to jointly determine at least one of the resource pattern information, the code division multiplexing group information, and the sequence information of the DMRS of the first data channel. For example, the carrier where the first data channel is located is used to determine at least one of one or more resource pattern information, one or more code division multiplexing group information, and one or more sequence information of the DMRS of the first data channel, and the third configuration information is used to indicate at least one of the one or more resource pattern information, the one or more code division multiplexing group information, or the one or more sequence information.

[0076] In a possible implementation manner of the first aspect or the second aspect, the first data channel is a data channel of a first radio access technology; and the second resource is used to carry a signal of a second radio access technology.

[0077] Based on the above scheme, the second resource is used to carry a signal of a second radio access technology, and the first data channel on the third resource excluding the second resource is a data channel of a first radio access technology, so that the above scheme can be applied to a scenario of two or more radio access technology spectrum sharing (for example, multi radio access technology spectrum sharing (MRSS)), and can avoid or reduce the mutual influence and / or mutual interference generated between the transmission of the data channel of the first radio access technology and the transmission of the signal of the second radio access technology in the scenario, so as to improve the data transmission performance.

[0078] Optionally, the resource pattern information of the reference signal of the first radio access technology can be implemented in various ways.

[0079] As an example, the resource pattern information of the reference signal of the first radio access technology is same as the resource pattern information of the reference signal of the second radio access technology; wherein the code division multiplexing group information of the reference signal of the first radio access technology is different from the code division multiplexing group information of the reference signal of the second radio access technology, and / or the sequence information of the reference signal of the first radio access technology is different from the sequence information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be same, so that the reference signals of different radio access technologies can be distinguished by different code division multiplexing groups and / or different sequences (e.g. orthogonal sequences), to save resource overhead.

[0080] As another example, the resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be different, so that the reference signals of different radio access technologies can be distinguished by different resource patterns, to reduce implementation complexity.

[0081] In a possible implementation form of the first aspect or the second aspect, the transport block size (TBS) corresponding to the first data channel is determined based on the third resource.

[0082] Based on the above scheme, the first communication device can determine that the TBS corresponding to the first data channel is determined based on the third resource which does not include the second resource, so that the first communication device can implement the reception or transmission of the first data channel based on the TBS associated with the third resource, and the reception performance of the receiver can be improved.

[0083] The third aspect of the present application provides a communication method applied to a first communication device, such as executed by the first communication device. The first communication device can be a communication device (e.g. a terminal device or a network device), or the first communication device can be a part of the communication device (e.g. a circuit or a chip responsible for communication function (e.g. a Modem chip, also known as a baseband chip, or a SoC chip or a SIP chip containing a modem core, etc.), or the first communication device can also be a logic module or software capable of implementing all or part of the functions of the communication device. In the method, the first communication device receives first configuration information, the first configuration information being used to configure a first resource of a first data channel; and the first communication device determines a TBS corresponding to the first data channel based on a third resource, the third resource being included in the first resource, and the third resource not including a second resource.

[0084] Based on the above scheme, the first configuration information received by the first communication device is used to configure the first resource of the first data channel, and the first communication device transmits or receives the first data channel on the third resource included in the first resource. Wherein, the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, which can improve the accuracy of TBS calculation, and further improve the transmission performance of the first data channel.

[0085] Optionally, after the first communication device determines the TBS of the first data channel based on the third resource, the first communication device can transmit or receive the first data channel on the third resource included in the first resource, so that the first communication device can realize the reception or transmission of the first data channel based on the TBS associated with the actually transmitted third resource, which can improve the transmission performance of the first data channel.

[0086] In a possible implementation of the third aspect, the second resource is a CCE resource, and / or a control channel DMRS resource.

[0087] Based on the above scheme, the third resource of the first data channel transmitted by the first communication device does not include the CCE resource and / or the DMRS resource on the control channel. Therefore, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource (i.e. the control channel resource) can be avoided or reduced.

[0088] In a possible implementation of the third aspect, the method further includes: the first communication device receives fourth configuration information, the fourth configuration information being used to indicate that the TBS corresponding to the first data channel is determined based on the third resource.

[0091] Based on the above scheme, the first configuration information sent by the second communication device to the first communication device is used to configure the first resource of the first data channel, and the first communication device transmits or receives the first data channel on the third resource included in the first resource. The TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, which can improve the accuracy of TBS calculation and further improve the transmission performance of the first data channel.

[0092] Optionally, the second communication device can communicate with the first communication device through the first data channel, and accordingly, the second communication device can transmit or receive the first data channel on the third resource included in the first resource, so that the second communication device and the first communication device can realize the reception or transmission of the first data channel based on the actual transmitted TBS associated with the third resource, which can improve the transmission performance of the first data channel.

[0093] In a possible implementation manner of the fourth aspect, the second resource is a CCE resource and / or a control channel DMRS resource.

[0094] Based on the above scheme, the third resource of the first data channel transmitted by the first communication device does not include the CCE resource and / or the DMRS resource on the control channel. Therefore, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource (i.e., the control channel resource) can be avoided or reduced.

[0095] In a possible implementation manner of the fourth aspect, the method further includes: the second communication device sends fourth configuration information, which is used to indicate that the TBS corresponding to the first data channel is determined based on the third resource.

[0096] Based on the above scheme, the second communication device can further send fourth configuration information to the first communication device, so that the first communication device can determine that the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource through the fourth configuration information, so that the first communication device can implement the reception or transmission of the first data channel based on the TBS associated with the third resource, the accuracy of TBS calculation can be improved, and the transmission performance of the first data channel can be improved.

[0125] The terminal can be widely applied to various scenarios, for example, device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, communication and sensing integration, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, an airplane, a ship, a robot, a mechanical arm, a smart home device, a sensor, etc. Embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

[0126] (2) Network device (or network element): can be a device in a wireless network, for example, the network device can be a RAN node (or device) for accessing a terminal device to a wireless network, which can also be referred to as a base station. At present, some examples of RAN devices are: base station, evolved NodeB (eNodeB), base station gNB (gNodeB) in 5G communication system, transmission reception point (transmission reception point or Transmit / Receive Point, TRP), evolved Node B (eNB), radio network controller (radio network controller, RNC), Node B (Node B, NB), home base station (for example, home evolved Node B, or home Node B, HNB), baseband unit (baseband unit, BBU), or wireless fidelity (wireless fidelity, Wi-Fi) access point AP, etc. In addition, in a network structure, the network device can include a centralized unit (central unit, CU) node, or a distributed unit (distributed unit, DU) node, or a RAN device including a CU node and a DU node.

[0129] In another possible scenario, multiple RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a CU, a DU, a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna processing unit (AAU) or a remote radio head (RRH).

[0130] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an open RAN (O-RAN or ORAN) system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, the CU-CP, the CU-UP, the DU and the RU are taken as examples for description in the present application. Any one of the CU (or the CU-CP, the CU-UP), the DU and the RU in the present application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0131] The communication between the access network device and the terminal device follows a certain protocol layer structure. The protocol layer can include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer can include at least one of a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media / medium access control (MAC) layer, or a physical (PHY) layer, etc. The user plane protocol layer can include at least one of a service data adaptation protocol (SDAP) layer, a PDCP layer, an RLC layer, a MAC layer, or a physical layer, etc. Among them, the physical layer can include a high physical layer (higher PHY or PHY-high) and a low physical layer (lower PHY or PHY-low).

[0132] For the correspondence between the network elements in the ORAN system and the protocol layer functions that can be implemented by the network elements, refer to Table 1 below.

[0133] Table 1

[0134] The network device can be other devices that provide wireless communication functions for terminal devices. Embodiments of the present application do not limit the specific technology and specific device form adopted by the network device. For the convenience of description, the embodiments of the present application do not limit.

[0135] The network device can also include a core network device, for example, including a mobility management entity (MME) in a fourth generation (4G) network, a home subscriber server (HSS), a serving gateway (S-GW), a policy and charging rules function (PCRF), a public data network gateway (P-GW), a network element such as an access and mobility management function (AMF), a user plane function (UPF), or a session management function (SMF) in a 5G network. In addition, the core network device can also include other core network devices in a 5G network and a next-generation network of the 5G network.

[0136] In the embodiments of the present application, the device for implementing the function of the network device can be the network device, or a device capable of supporting the network device to implement the function, such as a chip system, which can be installed in the network device. In the technical solutions provided in the embodiments of the present application, the device for implementing the function of the network device is taken as an example to describe the technical solutions provided in the embodiments of the present application.

[0137] (3) Configuration and pre-configuration: in the present application, configuration and pre-configuration will be used simultaneously. Configuration refers to that the network device sends some parameter configuration information or parameter values to the terminal device through a message or signaling, so that the terminal device determines the communication parameters or the resources in the transmission according to the values or information. Pre-configuration is similar to configuration, which can be parameter information or parameter values agreed by the network device and the terminal device in advance, or parameter information or parameter values adopted by the network device and / or the terminal device according to a standard protocol, or parameter information or parameter values pre-stored in the network device and / or the terminal device. The present application does not limit this.

[0138] Optionally, configuration can also be understood as indication.

[0139] Further, the values and parameters can be changed, updated or reconfigured.

[0140] (4) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" refers to one or more, and "multiple" refers to two or more. "And / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the cases of A alone, A and B together, and B alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or multiple items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC. In addition, unless otherwise specified, the ordinal numbers "first", "second", etc. mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, time sequence, priority or importance of the multiple objects.

[0141] (5) In the embodiments of the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface by other units or modules. "Sending" can also be understood as "output" of a chip interface, and "receiving" can also be understood as "input" of a chip interface.

[0142] In other words, sending and receiving can be between devices, such as between network devices and terminal devices, or within devices, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0143] It can be understood that the information may be processed as necessary between the source and the destination of the information transmission, such as encoding and modulation, but the destination can understand the valid information from the source. Similar expressions in the present application can be similarly understood, and will not be repeated here.

[0144] (6) In the embodiments of the present application, "indication" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. The information indicated by certain information (indication information described below) is referred to as to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can be achieved by means of the arrangement order of each information agreed in advance (for example, protocol predefined), thereby reducing the indication overhead to a certain extent. The present application does not limit the specific manner of indication. It can be understood that the indication information can be used to indicate the to-be-indicated information for the sender of the indication information, and the indication information can be used to determine the to-be-indicated information for the receiver of the indication information.

[0145] (7) Rate matching.

[0146] Rate matching is used in wireless communication systems to adjust the coded data bit rate to match the bit carrying capacity of the physical layer transmission resources. In communication systems such as LTE and NR systems, the rate matching process ensures that the number of coded bits matches the number of bits that the physical layer resource units can carry.

[0147] For example, rate matching involves the following steps:

[0148] ① Encoding: First, the data is channel encoded to generate coded bits (CB).

[0149] ② Bit selection: Then, by selecting part of the coded bit stream to match the number of bits that the physical layer resources can carry. This usually involves the insertion or deletion of bits to ensure that the data rate matches the bit carrying capacity of the physical layer resources.

[0150] ③ Interleaving: Interleaving is part of the rate matching process, which changes the output order of the bit stream, but does not involve the addition or deletion of bits.

[0151] The goal of rate matching is to optimize data transmission efficiency, avoid the number of data bits exceeding the carrying capacity of the physical layer resources, and at the same time ensure the reliability and efficiency of transmission.

[0152] Optionally, the time-frequency resources on which data is not mapped can be punctured after the time-frequency resources on which data is mapped.

[0153] Generally, in NR systems, "puncturing" is an implementation of a rate matching technique, mainly used to adjust the rate of the encoded data stream to adapt to different transmission requirements and channel conditions. The process of puncturing involves selectively deleting (or ignoring) part of the bits from the encoded bit stream to reduce the bit rate of the data stream to match the transmission resources of the physical layer. Specifically, when the number of encoded data bits exceeds the number of bits that the physical layer resources can carry, puncturing is needed to reduce the number of bits. The puncturing algorithm will select which bits to delete according to certain rules, which usually take into account the importance of the bits to minimize the impact on decoding performance.

[0154] In this application, except for special description, the same or similar parts between various embodiments can be mutually referred. In various embodiments of the present application, and various implementation manners / implementation methods / realization methods in each embodiment, if there is no special description and logical conflict, the terms and / or descriptions between different embodiments, and between various implementation manners / implementation methods / realization methods in each embodiment are consistent and can be mutually referred, and the technical features in different embodiments, and in various implementation manners / implementation methods / realization methods in each embodiment can be combined to form new embodiments, implementation manners, implementation methods, or realization methods according to their inherent logical relationship. The implementation manners of the present application described below do not constitute a limitation on the protection scope of the present application.

[0155] In order to facilitate understanding of the method provided by the embodiments of the present application, the system architecture of the method provided by the embodiments of the present application will be described below. It can be understood that the system architecture described in the embodiments of the present application is to more clearly illustrate the scheme of the embodiments of the present application, and does not constitute a limitation on the scheme provided by the embodiments of the present application.

[0156] In a possible implementation, the present application can be applied to a Narrow Band-Internet of Things (NB-IoT) system, an integrated sensing and communication (ISAC) communication system, a wireless local area network (WLAN), a short-range wireless communication system (such as a sidelink, wireless fidelity (Wi-Fi or WiFi), Bluetooth, and the like), a wired network, a vehicle to everything (V2X) communication system, a device-to-device (D2D) communication system, a vehicle networking communication system, a 4th generation (4G) mobile communication system (such as a long term evolution (LTE) system), an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), a 5th generation (5G) mobile communication system (such as a new radio (NR) system), a future evolved new radio (NR) wireless communication system, or other similar communication systems, and the like, without limitation. For example, the present application can be applied to an orthogonal frequency division multiplexing (OFDM) system in LTE, an OFDM system in NR, and a future OFDM system and an OFDM-like system, for example, the present application can be applied to three major application scenarios of the next generation 5G mobile communication system: enhanced mobile broadband (eMBB), ultra-reliable low latency communication (URLLC), and / or enhanced machine type communication (eMTC).

[0157] Referring to FIG. 1a, an architecture of a communication system 10 to which embodiments of the present application can be applied is shown. As shown in FIG. 1a, the communication system includes a RAN 100 and a core network 200, and optionally, the communication system 10 can further include an Internet 300. The RAN 100 includes at least one RAN node (e.g., 110a and 110b, collectively denoted as 110 in FIG. 1a) and at least one terminal (e.g., 120a-120j, collectively denoted as 120 in FIG. 1a). The RAN 100 can further include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1a). The terminal 120 is wirelessly connected to the RAN node 110, and the RAN node 110 is connected to the core network 200 through wire or wireless. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrated with the logical function of the core network device and the logical function of the RAN node. The terminals can be connected to each other and the RAN nodes can be connected to each other through wire or wireless.

[0158] FIG. 1b shows an example of an O-RAN system, which can include other components than those shown in the figure. As shown, an access network device (such as a RAN device, which can be an eNB or a gNB or a next generation access network device) communicates with a core network (CN) over a backhaul and communicates with a UE over an air interface.

[0159] In a possible implementation, the present application can be applied to a long term evolution (LTE) wireless communication system, an NR wireless communication system, and a future evolved new radio (NR) wireless communication system. For example, the present application can be applied to an orthogonal frequency division multiplexing (OFDM) system in LTE, an OFDM system in NR, and a future OFDM system and an OFDM-like system, etc.

[0160] As an example, the RAN node can be a satellite base station or a satellite, which is explained below in connection with FIGS. 1c-1g. FIGS. 1c and 1d are schematic diagrams of a communication system suitable for embodiments of the present application.

[0161] As shown in FIGS. 1c and 1d, the satellite base station provides communication services for the terminal. For example, the satellite base station transmits downlink data to the terminal, where the data is encoded using channel coding, and the channel-coded data is transmitted to the terminal after being modulated by constellation modulation. For another example, the terminal transmits uplink data to the satellite base station, where the uplink data can also be encoded using channel coding, and the encoded data is transmitted to the satellite base station after being modulated by constellation modulation. In addition, as shown in FIG. 1d, the satellite base station can also communicate with the ground base station, that is, the satellite can act as a base station, and also as a terminal.

[0162] In this application, the satellite can refer to a drone, a hot air balloon, a low-orbit satellite, a medium-orbit satellite, a high-orbit satellite, etc. The satellite can also refer to a non-ground base station or a non-ground device, etc.

[0163] It should be understood that the present application can be applied to a scenario in which network devices communicate with each other, and the scenario shown in FIG. 1d can also be regarded as an example of network devices communicating with each other, where the satellite and the base station can both be regarded as a network device.

[0164] As an implementation manner, the present application can be applied to a satellite inter-satellite link communication system. For example, the communication between satellite #1 and satellite #2 shown in FIG. 1d.

[0165] As shown in FIG. 1e, the satellite inter-satellite link communication system can be divided into two parts: an acquisition pointing tracking (APT) subsystem (including an APT module and an APT transmitter / receiver) and a communication subsystem (including a communication module and a transceiving antenna). The communication subsystem is mainly responsible for the transmission of inter-satellite information, and is the main body of the inter-satellite communication system; the APT system is mainly responsible for the acquisition, alignment and tracking between satellites. The direction of arrival of the incident signal can be determined, which is used for acquisition and adjustment of the direction of the transmitted wave aiming at the receiving direction, which is used for alignment. In the whole communication process, the APT is constantly adjusted for alignment and acquisition, which is used for tracking. In order to minimize the influence of attenuation and interference in the channel, while requiring high confidentiality and transmission rate, the APT must be adjusted in real time to adapt to changes constantly.

[0166] It should be understood that the current APT system is an optical system, which has the disadvantage of difficult optical alignment and the need for mechanical adjustment of the pointing direction. The current communication subsystem is mostly an optical communication system, and there are also some microwave band systems, which mostly use a single high-gain antenna. The current APT system and the communication subsystem are independent systems. The disadvantage is that optical communication is easily affected by vibration, etc., and the rate is unstable; the frequency of millimeter wave is low, the communication capacity is low, and the antenna needs to be mechanically adjusted for pointing.

[0167] As another implementation manner, the present application can be applied to a scenario in which terminal devices communicate with each other, for example, an Internet of Things communication system.

[0168] FIG. 1f is a schematic diagram of a wireless screen projection of an Internet of Things, which is applicable to the embodiments of the present application. A terminal device (for example, a smart phone) establishes a network connection with a television set. The smart phone transmits content that needs to be projected and displayed on the television set to the television set. After receiving the content transmitted by the smart phone, the television set displays the content on its display screen.

[0169] It should be understood that the screen projection scenario shown in FIG. 1f can be regarded as an example of terminal device-to-terminal device communication, in which the smart phone and the television set can both be regarded as a terminal device.

[0170] As yet another implementation manner, the present application can be applied to an integrated access and backhaul (IAB) system.

[0171] FIG. 1g is a schematic diagram of an IAB system, which is applicable to the embodiments of the present application. As shown in FIG. 1g, the IAB can include an IAB donor, an IAB node and a terminal. The link between the IAB donor and the IAB node is a backhaul link, and the link between the terminal and the IAB node is an access link. The present application can be applied to both parties of communication in the backhaul link, or both parties of communication in the access link.

[0172] It should be understood that the above-mentioned system application scenarios are only examples, and the present application can also be applied to other scenarios, which are not listed one by one here.

[0173] In a wireless communication system (for example, the system shown in any one of FIGS. 1a to 1g), the wireless communication resource generally includes time-frequency resources. In the following, the time-frequency resources will be introduced taking the NR system as an example. It should be understood that NR can be replaced by 5G or 5G NR.

[0174] 1. Numerology.

[0175] The 5G NR introduces the concept of Numerology, which includes sub-carrier spacing (SCS), and corresponding parameters such as symbol length, cycle prefix (CP) length, etc. Since there is a certain mapping relationship between SCS and symbol length, CP length, in some documents, SCS is also often used instead of Numerology.

[0176] For example, the parameters involved in Numerology are shown in Table 2.

[0177] Table 2

[0178] In Table 2, μ represents a subcarrier spacing index, or μ represents a numerology, CP length includes normal (Normal) CP length and extended (Extended) CP length, and FR represents a frequency range (FR).

[0179] 2. Frame structure.

[0180] In the NR system, the unit in time domain includes symbol, slot, subframe, half frame, frame, etc., wherein the time of one frame is 10 ms, one frame can be divided into 10 subframes numbered 0-9, and the subframes numbered 0-4 form one half frame, and the subframes numbered 5-9 form another half frame. The time of each subframe is 1 ms. Each subframe can include one or more slots, and each slot includes 14 symbols under normal CP and includes 12 symbols under extended CP.

[0181] For example, the number of slots included in each subframe is related to SCS, and the association is shown in Table 3.

[0182] Table 3

[0183] As shown in FIG. 2a, an example is a schematic diagram of a frame structure of 5G NR, which includes:

[0184] Frame: fixed length of 10 ms, frame number range: 0-1023.

[0185] Subframe: fixed length of 1 ms, subframe number range: 0-9.

[0186] Slot: when normal CP is used, the length is 14 symbols. Since the symbol length is not fixed, the slot length is also not fixed. When the SCS is 60 kHz, extended CP can also be used, and the slot length is 12 symbols. Optionally, the slot is the smallest unit of data scheduling.

[0187] Symbol: the length is not fixed and is related to SCS. Optionally, the symbol is the basic unit of modulation.

[0188] Generally, in the physical layer, one symbol can include a plurality of sampling points, and the sampling point can be the smallest time unit of the physical layer.

[0189] In addition, the scheduling time unit on the 5G NR data domain is a slot, the number of symbols contained in the slot is fixed, but the length of the symbol is related to the SCS. In the following, taking SCS of 30 kHz and 120 kHz as examples, the relationship between the frame, subframe, slot and symbol will be exemplarily described.

[0190] As shown in the examples of FIG. 2b and FIG. 2c, the relationship between the frame, subframe, slot and symbol corresponding to SCS of 30 kHz and 120 kHz respectively.

[0191] 3. Symbol type and slot format.

[0192] Generally, OFDM symbols include three types, which are:

[0193] Downlink (DL): represented by the letter D, used for downlink transmission.

[0194] Uplink (UL): represented by the letter U, used for uplink transmission.

[0195] Flexible (F): represented by the letter F, which can be used for uplink transmission, also can be used for downlink transmission, and also can be used as a guard period (GP) or reserved resource.

[0196] Optionally, each slot can be freely combined by the three types of symbols to form various slot formats.

[0197] As shown in the example of FIG. 2d, according to the protocol-defined slot format, the slot type can be divided into four cases (Case).

[0198] Case 1: only contains “D” symbols, which is also commonly referred to as a downlink-only slot (DL-only slot).

[0199] Case 2: only contains “U” symbols, which is also commonly referred to as a downlink-only slot (UL-only slot).

[0200] Case 3: only contains “F” symbols, which is also commonly referred to as a flexible-only slot (Flexible-only slot).

[0201] Case 4: a slot contains at least one “D” or “U” symbol, and there is also an “F” symbol in the slot.

[0202] In addition, as shown in FIG. 2d, Case 4 can be further divided into several sub-cases.

[0203] Case 4-1: a slot contains more “D” symbols and fewer “F” symbols.

[0204] Case 4-2: One slot contains more “U” symbols and less “F” symbols.

[0205] Case 4-3: One slot contains more “D” symbols and less “F” symbols and less “U” symbols.

[0206] Case 4-4: One slot contains more “U” symbols and less “F” symbols and less “D” symbols.

[0207] Case 4-5: One slot contains alternating “D”, “F” and “U” symbols.

[0208] As can be seen from the above examples, the slot format design of 5G NR can achieve uplink and downlink data changes at the symbol level, while in LTE, changes can only be made at the subframe level. This design is more flexible and also makes the slot type more diverse to adapt to different types of services in different scenarios.

[0209] 4. Self-contained slot.

[0210] Case 4-3, Case 4-4 and Case 4-5 in FIG. 2d are also called self-contained slots, which correspond to two structures of self-contained slots, respectively.

[0211] One structure is a DL-dominant slot: Case 4-3 in FIG. 2d, in which the slot is mainly used for downlink data transmission, and a small number of symbols are used for transmitting uplink control signals (such as hybrid automatic repeat request (HARQ) feedback of the downlink data) or sounding reference signals (SRS) through time division multiplexing, thereby shortening the downlink HARQ feedback delay.

[0212] The other structure is a UL-dominant slot: Case 4-4 in FIG. 2d, in which the slot is mainly used for uplink data transmission, and a small number of symbols are used for transmitting downlink control signals (such as uplink scheduling indication in the physical downlink control channel (PDCCH)) through time division multiplexing, thereby shortening the uplink scheduling delay.

[0213] Generally, in the design of self-contained slot, both network device and terminal device can switch uplink and downlink transmission in one slot, and ensure normal work after switching by reserving guard time and not transmitting or receiving any signal in the guard time.

[0214] 5. Mini-slot.

[0215] In order to further reduce the air interface delay, the protocol proposes the concept of micro-slot, whose time domain length can be less than 14 symbols. Compared with the scheduling of basic slots, the division in time domain of micro-slots is more fine-grained, and the scheduling delay is also shorter. The scheduling of micro-slots is usually also called non-slot based scheduling.

[0216] 6. Frequency domain resource.

[0217] Resource element (RE) is the smallest physical layer resource of 5G NR, which is 1 subcarrier in frequency domain and 1 OFDM symbol in time domain.

[0218] Resource block (RB) is the basic unit of channel resource allocation in frequency domain of 5G NR, and one RB can contain 12 subcarriers in frequency domain. Since the subcarrier spacing in 5G NR is variable, the actual bandwidth of RB is also variable.

[0219] Resource grid (RG) is a set of time-frequency resources, which is defined as follows in 5G NR: for different numerologies on each carrier, a RG is a set of resources of all subcarriers in frequency domain and all symbols in time domain with a length of one subframe, and the starting point of frequency domain is in RB granularity. Since different numerologies correspond to different SCS, and one RB is 12 subcarriers, for the same transmission bandwidth, the number of RBs contained in RG is different under different numerologies. RG is one subframe in time domain. Meanwhile, uplink and downlink RGs are defined respectively.

[0220] As shown in FIG. 2e, it is a schematic diagram of one implementation of resource division of RE, RB and RG. In FIG. 2e, one subframe in time domain can include a plurality of OFDM symbols; one resource element represents a resource of 1 subcarrier in frequency domain and 1 OFDM symbol in time domain; one resource block contains 12 subcarriers in frequency domain; and resource grid represents a set of time-frequency resources.

[0221] Common resource block (CRB) can be understood as a general term for all RBs in 5G NR, numbered from 0, and the center frequency point of the 0th subcarrier in CRB0 is also Point A.

[0222] Physical resource block (PRB) refers to the RBs contained in the bandwidth part (BWP) of a certain terminal device in 5G NR, also numbered from 0, and is the basic unit of data channel scheduling.

[0223] Resource block group (RBG) refers to the combination of a number of PRBs within the bandwidth part (BWP), also numbered from 0, and is the basic unit of data channel scheduling. An RBG can contain {2, 4, 8, 16} PRBs, and the specific number is related to the number of RBs in the BWP and the configuration options.

[0224] Resource element group (REG) is the basic unit of control channel resources. One REG is 12 subcarriers in the frequency domain, i.e., the width of one RB, and 1 OFDM symbol in the time domain. Optionally, the resource element group can be a resource unit group.

[0225] Control channel element (CCE) is the basic unit of control channel resource scheduling, and one CCE is composed of 6 REGs in the frequency domain.

[0226] As shown in FIG. 2f, it is a schematic diagram of the relationship between REG and CCE.

[0227] As described above, the definition of time-frequency resources in NR, the same definition can be used in future networks, or different definitions can be used. For example, future networks can define multiple subcarrier spacings, not limited to SCS in 5G. One slot can include one or more symbols, one RB can include one or more subcarriers, etc.

[0228] Wherein, the PDCCH resource is finally mapped to the RB, but a PDCCH will occupy more RBs, and it is not very convenient to describe the resource occupied by the PDCCH in RB, so there are concepts of REG and CCE. A CCE corresponds to 6 REGs, and each REG corresponds to an RB, as shown in the following figure. The resource that the PDCCH can occupy and the resource that the PDCCH actually occupies are described by CCE. For example: in a 100MHz (273RB) bandwidth, when the subcarrier interval in a symbol is 30kHz, there are at most 45 CCEs (270RBs).

[0229] Optionally, the NR system defines that the PDCCH can use {1, 2, 4, 8, 16} consecutive CCEs, wherein the number of CCEs used is also called the aggregation level, as shown in the following table. The worse the wireless channel quality is, the larger the aggregation level of the PDCCH required to ensure the transmission quality of the PDCCH. The more CCEs used by the PDCCH, that is, the higher the aggregation level, the better the demodulation performance, but it may also cause resource waste. The gNodeB determines the aggregation level used by a certain PDCCH according to factors such as channel quality. For example, the terminal device at the edge of the cell should use a PDCCH format with a larger CCE aggregation level, to exchange resources for demodulation performance; the terminal device at the center of the cell can use a PDCCH format with a smaller CCE aggregation level, to save time-frequency resources.

[0230] For example, the implementation of the CCE aggregation level can refer to the manner shown in Table 4 below.

[0231] Table 4

[0232] Optionally, the PDCCH is formatted on the time-frequency resource as follows:

[0233] In the time domain: occupy {1, 2, 3} symbols of 1 slot.

[0234] In the frequency domain: it can be the full bandwidth, or it can be configured by parameters.

[0235] Generally, the time-frequency location of DMRS on PDCCH (i.e. DMRS for PDCCH) is fixed on subcarrier 1, 5, 9 of each REG of PDCCH corresponding symbol. In order to more effectively demodulate PDCCH, the DMRS of one PDCCH is mapped to one of every 4 subcarriers in the REG (i.e. subcarrier 1, 5, 9 of each REG), that is, the introduced DMRS accounts for 1 / 4 of the PDCCH overhead, and the density of this reference signal is higher than 1 / 6 of LTE. Using PDCCH-specific DMRS can increase the overhead of the reference signal, but also brings benefits, such as being able to beamform for each terminal device. Through beamforming of PDCCH, the coverage and performance of NR PDCCH are improved, which also conforms to the beam-centered design philosophy of NR.

[0236] 7. Transmit or receive

[0237] Physical reception link control channel (PRxCCH): It is a physical layer control channel. Generally, the standard protocol is described from the perspective of the terminal device, that is, the physical layer control channel received by the terminal device, which is similar to the PDCCH in LTE and 5G. PRxCCH can be a newly introduced physical layer control channel in the next generation communication system (such as 6G). Of course, 6G can also use PDCCH to represent the physical downlink control channel or physical transmission link control channel of the terminal device.

[0238] Physical reception shared channel (PRxSCH): It is a physical layer data channel. Generally, the standard protocol is described from the perspective of the terminal device, that is, the physical layer data channel received by the terminal device, which is similar to the PDSCH in LTE and 5G. PRxSCH can be a newly introduced physical layer data channel in 6G. Of course, future communications such as 6G can also use PDSCH to represent the physical downlink data channel or physical reception link data channel of the terminal device.

[0239] Physical transmission link control channel (PTxCCH): a kind of physical layer control channel. Generally, the standard protocol is described from the perspective of terminal equipment, that is, the physical layer control channel sent by the terminal equipment, which is similar to the physical uplink control channel (PUCCH) in LTE and 5G. PTxCCH can be a new physical layer control channel introduced in 6G. Of course, future communications such as 6G may still use PUCCH to represent the physical uplink control channel or physical transmission link control channel of the terminal equipment.

[0240] Physical transmission shared channel (PTxSCH): a kind of physical layer data channel. Generally, the standard protocol is described from the perspective of terminal equipment, that is, the physical layer data channel sent by the terminal equipment, which is similar to the physical uplink shared channel (PUSCH) in LTE and 5G. PTxSCH can be a new physical layer data channel introduced in 6G. Of course, future communications such as 6G may still use PUSCH to represent the physical uplink data channel or physical reception link data channel of the terminal equipment.

[0241] Optionally, for downlink, it can be described as receiving from the perspective of terminal equipment; for uplink, it can be described as sending from the perspective of terminal equipment.

[0242] At present, in the communication process of different communication devices, the data sender can send data through the data channel, and correspondingly, the data receiver can receive data through the data channel to realize the data transmission process. However, in the above data transmission process, how to improve the data transmission performance is a technical problem to be solved.

[0243] As an example, taking a communication process between a network device and a terminal device as an example, if there is a conflict between resources of two or more wireless access technologies, a channel transmission or a signal transmission (denoted as transmission 1) of one wireless access technology can be evaded by resource scheduling of another wireless access technology (denoted as transmission 2) to improve the transmission performance of the transmission 1. Generally, the channel priority of the transmission 1 is higher than the channel priority of the transmission 2, or the signal priority of the transmission 1 is higher than the signal priority of the transmission 2. For example, the network device can realize active avoidance of PDSCH of LTE from Synchronization Signal Block (SSB) of NR, or active avoidance of PDSCH of NR from cell-specific reference signal (CRS) of LTE, and the like, by resource scheduling. Wherein, the PDCCH and the PDSCH of LTE and NR share resources on demand. Correspondingly, in the above implementation example, in the case that the transmission 1 is a transmission of a data channel, this way can improve the data transmission performance on the data channel.

[0244] However, in the above example, the resources occupied by the transmission 1 will completely evade the resources occupied by the transmission 2, and this way will cause the transmission 2 to be unavailable, and further cause low spectrum efficiency.

[0245] As another example, taking a downlink communication process between a network device and a terminal device as an example, in an NR system, the downlink data channel can be a PDSCH, and the network device can instruct a certain terminal device (denoted as terminal device 1) to perform rate matching on certain specific resources on the PDSCH resources, i.e., the specific resources are not used for data transmission. In this way, the data transmission of the NR PDSCH can not be interfered by the specific resources, and / or the signals on the specific resources can not be interfered by the PDSCH, to improve the data transmission performance of the NR PDSCH and the transmission performance of the signals on the specific resources.

[0246] For example, on PDSCH, different terminal devices (or different users) can transmit respective DMRSs through different DMRS code division multiplexing groups (CDM groups), and generally, DMRSs of different DMRS CDM groups are located in the same symbol. Correspondingly, the specific resource can include a resource occupied by a DMRS code division multiplexing group (CDM group) without data transmission, which is used for transmission of other DMRS CDM groups other than the DMRS CDM group used by the terminal device 1, and interference avoidance of DMRSs between users scheduled by NR multi-user (MU) scheduling through rate matching of the specific resource is achieved.

[0247] For another example, on PDSCH, the specific resource can include a resource occupied by a CRS of LTE, and rate matching under coexistence of LTE and NR is achieved through rate matching of the specific resource. Through the method, the CRS of LTE can be free from interference of PDSCH, and accuracy of channel estimation based on the CRS by a user of LTE is ensured. Through the method, PDSCH can be free from interference of the CRS of LTE, and communication performance of PDSCH is ensured.

[0248] For another example, on PDSCH, the specific resource can include a resource at the RB-symbol level, and rate matching of an NR CORESET is achieved through rate matching of the specific resource. Through the method, a control resource set CORESET can be free from interference of PDSCH, and communication performance of a control channel is ensured. Through the method, PDSCH can be free from interference of the CORESET, and communication performance of PDSCH is ensured.

[0249] For another example, on PDSCH, the specific resource can include a resource of a ZP CSI-RS, and rate matching of an NR CSI-RS resource is achieved through rate matching of the specific resource.

[0250] However, in the above examples, only rate matching manners of PDSCH of NR are provided, and use scenarios are limited.

[0251] To solve the above problems, the present application provides a communication method and related devices, which will be described in detail below with reference to the accompanying drawings.

[0252] Please refer to FIG. 3, which is an implementation schematic diagram of a communication method provided by the present application, and the method includes the following steps.

[0253] It should be understood that, in the following, the method flowchart is exemplified by taking different communication devices (e.g., the interaction between the first communication device and the second communication device, the interaction between the third communication device and the fourth communication device, etc.) as the execution subject of the interaction as an example, but the application does not limit the execution subject of the interaction. For example, any communication device (e.g., the first communication device, the second communication device, the third communication device, or the fourth communication device) can be a communication device, or a chip, a baseband chip, a modem chip, a SoC chip containing a modem core, a SIP chip, a communication module, a chip system, a processor, a logic module, or software in a communication device. Optionally, the communication device can be a terminal device or a network device (e.g., the network device can be an access network device, an access network network element, etc.).

[0254] As an example, in FIG. 3 and / or FIG. 6, the first communication device can be a terminal device and the second communication device can be a network device, or the first communication device and the second communication device are both network devices. For example, the network device can be an access network device, a communication device (e.g., at least one of a CU, a DU, and a RU) in an ORAN system.

[0255] As another example, in FIG. 3 and / or FIG. 6, the first communication device and the second communication device are both terminal devices, that is, the scheme shown in FIG. 3 and / or FIG. 6 can be applied to a sidelink communication scenario.

[0256] S301. The second communication device sends first configuration information, and correspondingly, the first communication device receives the first configuration information. The first configuration information is used to configure a first resource of a first data channel.

[0257] S302. The second communication device sends second configuration information, and correspondingly, the first communication device receives the second configuration information. The second configuration information is used to configure a second resource.

[0258] S303. The first communication device sends or receives the first data channel on a third resource, wherein the third resource is included in the first resource, and the third resource does not include the second resource.

[0259] Optionally, the first configuration information and the second configuration information can be the same configuration information, or can be different configuration information.

[0260] Optionally, the first configuration information and / or the second configuration information can be physical layer signaling, such as downlink control information (DCI), or high layer signaling, such as MAC signaling, or RRC signaling, etc.

[0261] Optionally, the step S301 and the step S302 can be performed simultaneously, or the step S301 can be performed first and then the step S302, or the step S302 can be performed first and then the step S301. The order of the step S301 and the step S302 is not limited in the present application.

[0262] Optionally, the third resource is included in the first resource. It can be understood that the third resource is a resource in the first resource, or the third resource is a subset of the first resource, or the third resource includes one or more resource units located in the first resource.

[0263] Optionally, the third resource does not include the second resource. It can be understood that, among one or more resource units included in the third resource, there is at least one resource unit different from one or more resource units included in the second resource; or, among one or more resource units included in the third resource, there is no overlap with one or more resource units included in the second resource; or, the resource in the third resource does not include the resource in the second resource.

[0264] It should be noted that the first communication device transmits or receives the first data channel on the third resource. It can be understood that the first communication device receives data and / or signals of the first data channel on the third resource, or the first communication device transmits data and / or signals of the first data channel on the third resource.

[0265] As an example, taking the process of receiving the first data channel by the first communication device as an example. In this process, the first communication device can determine the second resource (i.e., the time-frequency resource on which data is not mapped) according to the second configuration information, and when the first communication device receives data on the first data channel, the first communication device can receive data on the third resource excluding the second resource; in other words, the transmitting end can perform rate matching on data based on the second resource, i.e., the transmitting end can not transmit data on the second resource, and correspondingly, the first communication device can not receive data on the second resource.

[0266] As another example, taking the process of transmitting the first data channel by the first communication device as an example. In this process, the first communication device can determine the second resource (i.e., the time-frequency resource on which data is not mapped) according to the second configuration information, and when the first communication device transmits data on the first data channel, the first communication device can transmit data on the third resource excluding the second resource; in other words, the first communication device can perform rate matching on data based on the second resource, i.e., the first communication device can not transmit data on the second resource, and correspondingly, the receiving end can not receive data on the second resource.

[0267] From the above process, it can be known that for the transceiver, the second resource can be a time-frequency resource on which data is not mapped.

[0268] For example, for the sending end, the sending end does not map data on the second resource (or determines not to map data on the second resource) through rate matching.

[0269] For example, for the sending end, the sending end can puncture (or delete, ignore, etc.) the bits carried by the second resource after mapping data on the first resource.

[0270] For example, for the receiving end, the receiving end can receive data on a third resource that does not include the second resource.

[0271] For example, for the receiving end, the receiving end ignores (or skips) one or more resource units in the first resource that overlap with the second resource in the process of receiving data on the first resource.

[0272] Optionally, in the above process, the communication device that communicates with the first communication device on the first data channel can be the communication device (for example, the second communication device) that sends the first configuration information to the first communication device, or can be another communication device, which is not limited here.

[0273] Based on the scheme shown in FIG. 3, the first configuration information received by the first communication device in step S301 is used to configure the first resource of the first data channel, and the second configuration information received by the first communication device in step S302 is used to configure the second resource; thereafter, in step S303, the first communication device transmits or receives the first data channel on a third resource in the first resource, which does not include the second resource. In this way, the first communication device can implement the transmission of the data channel on the third resource in the first resource except for the specified second resource, and can avoid or reduce the mutual influence and / or mutual interference between the transmission of the data channel and the transmission of other signals on the second resource, so as to improve the data transmission performance.

[0274] In a possible implementation of the method shown in FIG. 3, the second resource is used to carry signals of a second radio access technology, and the first data channel on the third resource that does not include the second resource is a data channel of a first radio access technology, so that the above scheme can be applied to a scenario of spectrum sharing of two or more radio access technologies (for example, MRSS), and can avoid or reduce the mutual influence and / or mutual interference between the transmission of the data channel of the first radio access technology and the transmission of the signals of the second radio access technology in the scenario, so as to improve the data transmission performance.

[0275] Optionally, the third resource can not include other resources in addition to the second resource configured by the second configuration information. The present application does not limit this.

[0276] For example, the third resource does not include a DMRS CDM group resource used by the first communication device, and interference avoidance of the DMRS is achieved by rate matching on the DMRS CDM group resource.

[0277] Here, the DMRS CDM group (CDM group) can also be referred to as CDM group (CDM group) for short.

[0278] For another example, the third resource does not include a DMRS CDM group resource used by the first communication device, and interference avoidance of the DMRS between users in MU scheduling in the first radio access technology is achieved by rate matching on the DMRS CDM group resource.

[0279] For another example, the third resource does not include a resource occupied by the CRS of the LTE, and rate matching under coexistence of the LTE and the first radio access technology is achieved by rate matching on the resource occupied by the CRS of the LTE.

[0280] For another example, the third resource does not include a RB-symbol level resource, and rate matching of the CORESET of the first radio access technology is achieved by rate matching on the RB-symbol level resource.

[0281] For another example, the third resource does not include a ZP CSI-RS resource, and rate matching of the CSI-RS resource of the first radio access technology is achieved by rate matching on the ZP CSI-RS resource.

[0282] For example, the first radio access technology can be a future network, including but not limited to 6G, 5.5G, the next generation network of 5G, etc. The second radio access technology can be NR, 5G, 5G NR, LTE, 4G, etc.

[0283] In a possible implementation of the method shown in FIG. 3, the second resource is a CCE resource, and / or a control channel DMRS resource. Specifically, the third resource of the first data channel transmitted by the first communication device does not include the CCE resource and / or the DMRS resource on the control channel. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource (i.e., the control channel resource) can be avoided or reduced.

[0284] Optionally, in the control channel, the second resource is a first part of resources in the control channel, the first part of resources being one or more CCE resources, or the first part of resources being one or more DMRS resources in the control channel, or the first part of resources being one or more CCE resources and one or more DMRS resources in the control channel. In other words, in the above scheme, the third resource of the first data channel transmitted by the first communication device does not include the first part of resources of the control channel, i.e., the first data channel transmitted by the first communication device can avoid the first part of resources of the control channel. In this way, while avoiding or reducing the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource, the data transmission can also be performed as much as possible using the resources of the control channel to improve the resource utilization and the spectrum efficiency.

[0285] Optionally, in the control channel, the second resource is a first part of resources in the control channel, the first part of resources being one or more CCE resources, or the first part of resources being one or more DMRS resources in the control channel, or the first part of resources being one or more CCE resources and one or more DMRS resources in the control channel. The control channel can further include a second part of resources, and the second resource does not include the second part of resources. In other words, in the above scheme, the third resource of the first data channel transmitted by the first communication device does not include the first part of resources of the control channel and includes part or all of the second part of resources of the control channel, i.e., the first data channel transmitted by the first communication device can avoid the first part of resources of the control channel but not the second part of resources of the control channel. In this way, while avoiding or reducing the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resource, the data transmission can also be performed as much as possible using the resources of the control channel to improve the resource utilization and the spectrum efficiency.

[0286] In a possible implementation of the method shown in FIG. 3, the second configuration information received by the first communication device in step S302 includes at least one of the following:

[0287] first information for indicating CCE resources contained in the second resource;

[0288] second information for indicating DMRS resources contained in the second resource; or

[0289] third information for indicating a resource pattern of RB-symbol level resources of rate matching, wherein the second resource is a resource in the resource pattern of the RB-symbol level resources.

[0290] Therefore, the second configuration information for configuring the second resource can include the at least one of the above to implement the configuration of the second resource.

[0291] Optionally, in the second configuration information, the first information includes at least one of the following:

[0292] first indication information for indicating a frequency domain position and / or a time domain position of a CORESET corresponding to the CCE resource included in the second resource;

[0293] second indication information for indicating a mapping manner of a CCE-REG in the CORESET corresponding to the CCE resource included in the second resource;

[0294] third indication information for indicating an interleaving parameter of the CCE-REG in the CORESET corresponding to the CCE resource included in the second resource;

[0295] fourth indication information for indicating at least one of whether the CCE resource included in the second resource is interleaved, a REG bundling size (for example, a parameter L described later) of the CCE resource included in the second resource, and a size of interleaving (for example, a parameter R described later) of the CCE resource included in the second resource;

[0296] fifth indication information for indicating a resource position of the CCE resource included in the second resource; or

[0297] sixth indication information for indicating that the CCE resource included in the second resource is not used for mapping the first data channel.

[0298] Therefore, the first information for determining the CCE resource included in the second resource can include the at least one of the above to improve flexibility of the scheme implementation.

[0299] Optionally, the fifth indication information includes at least one of the following:

[0300] a bit map corresponding to the CCE resource included in the second resource;

[0301] a starting CCE index and / or a CCE number of the CCE resource included in the second resource;

[0302] a bit map corresponding to a CCE group to which the CCE resource included in the second resource belongs; or

[0303] a starting CCE group index and / or a CCE group number of the CCE group to which the CCE resource included in the second resource belongs.

[0304] Therefore, the fifth indication information used for indicating the resource location of the CCE resource contained in the second resource can include the at least one of the above, so as to improve the flexibility of the scheme implementation.

[0305] Optionally, in the second configuration information, the second information includes at least one of the following:

[0306] The seventh indication information is used for configuring a resource pattern of a ZP CSI-RS resource or a resource pattern of a DMRS resource contained in the second resource, and the resource pattern of the ZP CSI-RS resource is the same as the resource pattern of the DMRS resource of the control channel;

[0307] The eighth indication information is used for configuring a time domain location of the DMRS resource contained in the second resource; or

[0308] The ninth indication information is used for configuring a frequency domain location of the DMRS resource contained in the second resource.

[0309] Therefore, the second information used for determining the DMRS resource contained in the second resource can include the at least one of the above, so as to improve the flexibility of the scheme implementation.

[0310] Optionally, the eighth indication information is used for indicating any one of the following:

[0311] A first bit map used for determining a symbol location of the second resource;

[0312] At least one of a starting time unit location, a time unit quantity, and a time domain density of the second resource;

[0313] A second bit map used for indicating an association relationship between the symbol location of the second resource and one or more candidate symbol locations; or

[0314] A second index corresponding to the starting time unit location of the second resource, the second index being used for indicating one of one or more starting time unit locations.

[0315] Therefore, the eighth indication information used for indicating the time domain location of the DMRS resource contained in the second resource can include the at least one of the above, so as to improve the flexibility of the scheme implementation.

[0316] Optionally, the ninth indication information is used for indicating any one of the following:

[0317] At least one of a starting frequency domain unit location and a frequency domain unit quantity of the second resource;

[0318] An RBG index to which the second resource belongs;

[0319] a third index corresponding to a starting frequency domain unit position of the second resource, the third index being used to indicate one of the one or more starting frequency domain unit positions;

[0320] a fourth index corresponding to a number of frequency domain units of the second resource, the fourth index being used to indicate one of the one or more numbers of frequency domain units.

[0321] Therefore, the ninth indication information used to indicate the frequency domain position of the DMRS resource contained in the second resource can include the at least one described above, so as to improve the flexibility of the implementation scheme.

[0322] As can be known from the foregoing description, the second resource can be implemented in various ways, such as at least one of the following ways. For example, the second resource can be a CCE resource. For another example, the second resource can be a control channel DMRS resource. For another example, the second resource can be a CCE resource and a control channel DMRS resource. The various information contained in the second configuration information will be described exemplarily in combination with the above-mentioned various implementation manners.

[0323] Manner one, the second resource is a CCE resource.

[0324] Optionally, the second resource can be a time-frequency resource without mapping data, or a rate-matched resource.

[0325] In the manner one, the second resource without mapping data can be a CCE resource corresponding to a CORESET.

[0326] As shown in the example of FIG. 4a, the time domain resource of the first data channel of the first radio access technology includes 6 time units (for example, symbol indexes are 0, 1, 2, 3, 4, and 5) in FIG. 4a, and the second resource without mapping data is located on the partial frequency domain resources of the 2nd and 3rd symbols (for example, frequency domain units 3, 4, 5, 7, 8, and 9 in FIG. 4a), and the other resources are third resources.

[0327] Optionally, the ith frequency domain unit in the present application can refer to a frequency domain unit i, or a frequency domain unit corresponding to a frequency domain unit number i.

[0328] Optionally, the frequency domain unit can indicate one or more resources on one or more frequency domains, including one or more subcarriers, one or more subcarrier groups, one or more resource blocks, one or more physical resource blocks, one or more resource block groups, one or more partial bandwidths, or other implementation manners specified in standards / protocols.

[0329] Optionally, the present application takes an example of one frequency domain unit including 12 subcarriers for illustration, and similar schemes for one frequency domain unit including other numbers of subcarriers are not described herein.

[0330] Optionally, the resource unit can be a minimum unit of time-frequency resource, and can include one or more resources in the time-frequency domain, such as one or more symbols in the time domain and one or more subcarriers in the frequency domain. For example, a resource unit can be a resource of one symbol in the time domain and one subcarrier in the frequency domain. For example, the resource unit can be a resource element (RE), which can be in one or more resource grids (RGs); or the resource unit can also be other implementation manners specified by standards / protocols.

[0331] Optionally, the time unit can be a frame, a subframe, a slot, a sub-slot, a symbol, a symbol group, etc. The time unit can also be understood as a time domain unit.

[0332] For example, the second communication device can configure the CCE resource without mapping data through common radio resource control (common RRC) signaling or group downlink control information (group DCI), so as to inform one or more first communication devices in the cell to perform rate matching on the CCE resource, i.e., the one or more first communication devices can determine the CCE resource without mapping data.

[0333] As described above, the second configuration information for configuring the second resource can include the first information, and the first information indicates the CCE resource included in the second resource.

[0334] As an example, the first information can include first indication information and fifth indication information. The first indication information is used to indicate configuration parameters of a CORESET corresponding to the CCE resource, and the fifth indication information is used to indicate a resource location (hereinafter, the resource location is taken as a resource number for example) of the CCE resource in the CORESET. The configuration parameters of the CORESET can include frequency domain location information and / or time domain location information. The frequency domain location information can include a starting RB location and / or a number of RBs, and the time domain location information can include a starting symbol number and / or a number of symbols. In this way, the first communication device can determine the CORESET corresponding to the CCE resource.

[0335] As shown in the example of FIG. 4b, each CCE corresponds to 6 REGs in the frequency domain. When the number of symbols is 1, the CCE number can be numbered by referring to CCE0, CCE1, … shown in FIG. 4b.

[0336] As shown in the example of FIG. 4c, each CCE corresponds to 6 REGs in the frequency domain. When the number of symbols is 2, the CCE number can be numbered by referring to CCE0, CCE1, CCE2, … shown in FIG. 4c.

[0337] As shown in the example of FIG. 4d, each CCE corresponds to 6 REGs in the frequency domain, and when the number of symbols is 3, the CCE numbers can be numbered according to CCE0, CCE1, CCE2, CCE3, and so on shown in FIG. 4d.

[0338] In addition, the fifth indication information can be implemented in the following multiple ways.

[0339] In method A, the fifth indication information indicates a bitmap of CCE indexes. For example, 0 represents no rate matching, and 1 represents rate matching. Alternatively, 0 represents mapping data, 1 represents no mapping data, or vice versa.

[0340] In method B, the fifth indication information indicates a starting CCE index and a number of CCEs without mapping data, to determine the CCEs for rate matching.

[0341] Optionally, the CCE index can also be referred to as a CCE number.

[0342] Compared with method A, the overhead can be reduced, but the flexibility is not as high as that of method 1, and method 2 can only indicate the consecutive CCE numbers without mapping data.

[0343] In method C, the fifth indication information indicates a bitmap of CCE groups. Each CCE group includes one or more CCEs.

[0344] Optionally, the size of the CCE group can be predefined by a protocol or signaled to the first communication device by the second communication device. Accordingly, the first communication device can determine the number of CCE groups according to the total number of CCEs and the size of the CCE group. For example, the number of CCE groups is the upward rounding or downward rounding of the total number of CCEs / the size of the CCE group.

[0345] Optionally, the second communication device indicates the number of bits of the bitmap of the CCE group to the first communication device. For example, 0 represents no rate matching, and 1 represents rate matching. Alternatively, 0 represents mapping data, 1 represents no mapping data, or vice versa.

[0346] It can be seen that, compared with method A or method B, method C can further reduce the indication overhead.

[0347] In method D, the fifth indication information indicates a starting CCE group index and / or a number of CCE groups.

[0348] For example, the fifth indication information is used to indicate a starting CCE group index (CCE group index). The number of CCE groups can be pre-defined by a protocol, such as 1, 2, 4, or 8, etc.

[0349] For example, the fifth indication information is used to indicate the number of CCE groups without mapping data. The starting CCE group index (CCE group index) can be pre-defined by a protocol, such as the starting CCE group index being CCE group 0.

[0350] Optionally, one CCE group includes one or more CCEs. The size of a CCE group can be pre-defined by a protocol or signaled by the second communication device to the first communication device. The first communication device can determine the number of CCE groups according to the total number of CCEs and the size of a CCE group.

[0351] Optionally, the number of CCE groups is the ceiling or floor of the total number of CCEs / the size of a CCE group. The second communication device indicates the starting CCE group index and the number of CCE groups without mapping data to the first communication device.

[0352] Compared with the mode A or the mode B or the mode C, the mode D can further reduce the indication overhead.

[0353] As an example, the first information can include second indication information used to indicate a mapping manner of CCE-REG in a CORESET corresponding to the CCE resource.

[0354] Generally, a control resource set is composed of resource blocks in the frequency domain and symbols in the time domain. A control channel element is composed of 6 resource element groups (REGs), and a resource element group is equal to a resource block during one OFDM symbol. The resource element groups in the control resource set are numbered in an increasing order in a time-first manner, starting from 0 for the first OFDM symbol and the smallest numbered resource block in the control resource set.

[0355] Optionally, one first communication device can configure one or more control resource sets, and each control resource set can only be associated with one CCE-to-REG mapping relationship.

[0356] Optionally, the CCE-to-REG mapping manner can include at least one of the following: whether to be interleaved, a REG bundle size, or a CCE interleaving size.

[0357] Optionally, the CCE-to-REG mapping of a control resource set can be interleaved or non-interleaved, and described by a REG bundle:

[0358] - REG bundle i is defined as REGs{iL,iL+1,…,iL+L-1}, where L is the size of the REG bundle, and is the number of REGs in the CORESET.

[0359] - CCE j includes REG bundle {f(6j / L),f(6j / L+1),…,f(6j / L+6 / L-1)} where f(·) is an interleaver.

[0360] Optionally, for non-interleaved mapping of CCE to REG, L=6, f(x)=x.

[0361] Optionally, for interleaved mapping of CCE to REG, L∈{2,6} when , the interleaver f(x) satisfies:

[0362] Optionally, the size of interleaving R∈{2,3,6}.

[0363] As another example, the first information can include third indication information, the third indication information being used for indicating at least one of the following: whether the CCE resources included in the second resource are interleaved, a size of REG bundle corresponding to the CCE resources included in the second resource, or a size of interleaving corresponding to the CCE resources included in the second resource.

[0364] Optionally, the interleaving parameter can include at least one of the following: whether to interleave, a size of REG bundle, or a size of CCE interleaving.

[0365] Optionally, the interleaving parameter can also be understood as configuration information of CCE-REG mapping.

[0366] As another example, the first information can include fourth indication information, the fourth indication information being used for indicating at least one of the following: whether the CCE resources included in the second resource are interleaved, a size of REG bundle corresponding to the CCE resources included in the second resource, or a size of interleaving corresponding to the CCE resources included in the second resource.

[0367] Optionally, if the parameter of whether to interleave is not configured, it can be defaulted to not interleaving.

[0368] Optionally, if the size of REG bundle is not configured, it can be defaulted to 6.

[0369] Optionally, if the size of interleaving is not configured, it can be defaulted to 2 or 3 or 6.

[0370] As another example, the first information can comprise sixth indication information, which is used to indicate that the control channel element (CCE) resources contained in the second resource are not used to map the first data channel.

[0371] For example, the second communication device can configure the CORESET and the CCE through high layer signaling, and indicate the CCE numbers which are not mapped with data through physical layer signaling (i.e., the sixth indication information is physical layer signaling).

[0372] For another example, the second communication device can configure the CORESET and the CCE through RRC signaling, and indicate the CCE numbers which are not mapped with data through DCI (i.e., the sixth indication information is DCI).

[0373] For another example, the second communication device can configure the CORESET and the CCE through high layer signaling, and configure the CCE numbers which are not mapped with data through high layer signaling (i.e., the sixth indication information is high layer signaling).

[0374] For another example, the second communication device can configure the CORESET and the CCE through RRC signaling, and configure the CCE numbers which are not mapped with data through MAC CE (i.e., the sixth indication information is MAC CE).

[0375] It should be understood that the high layer signaling mentioned above can be RRC signaling, MAC CE, or other signaling / message / information defined in future standards. The physical layer signaling mentioned above can be DCI, or other signaling / message / information defined in future standards.

[0376] As described above, the second configuration information used to configure the second resource can comprise third information, and the third information is used to indicate the resource pattern of the RB-symbol level resource which is rate matched, wherein the CCE resources contained in the second resource are resources in the resource pattern of the RB-symbol level resource.

[0377] For example, the third information can be RRC configuration information, which is used to configure the rate matched resource, and the RRC configuration information comprises the resource pattern of the RB-symbol level. For example, the RRC configuration information can indicate the bit map of the frequency domain resource (e.g., RB bitmap) and / or the bit map of the time domain resource (e.g., Symbol bitmap). Optionally, the resource corresponding to the pattern of PDCCH CCE or PDCCH DMRS in the RB-symbol in the pattern configured by the RRC configuration information needs to be rate matched.

[0378] Optionally, the rate matched resource configured by the RRC configuration information can be periodic, semi-persistent, or aperiodic resource.

[0379] Optionally, the RRC configuration information can configure one or more rate-matched resource identifiers, and the dynamic rate matching is performed by activating one or more rate-matched resource identifiers in the DCI (i.e., the third information can include the RRC configuration information and the DCI).

[0380] In the second way, the second resource can be a control channel DMRS resource.

[0381] Optionally, the second resource can be a time-frequency resource without data mapping or a rate-matched resource.

[0382] In the first way, the second resource without data mapping can be a control channel DMRS resource.

[0383] As shown in the example of FIG. 5a, the time-domain resource of the first data channel of the first radio access technology includes 6 time units (e.g., symbol indexes 0, 1, 2, 3, 4, and 5) in FIG. 5a, the second resource without data mapping includes a part of the frequency-domain resource of the fourth symbol (e.g., frequency-domain units 5, 6, 7, 8, and 9 in FIG. 5a), and the other resource is the third resource.

[0384] For example, the second communication device can configure the control channel DMRS resource without data mapping through common radio resource control (common RRC) signaling or group downlink control information (group DCI), so as to inform one or more first communication devices in the cell to perform rate matching on the control channel DMRS resource, i.e., the one or more first communication devices can determine the control channel DMRS resource without data mapping.

[0385] As described above, in addition to the first information, the second configuration information for configuring the second resource can also include the second information indicating the DMRS resource.

[0386] As an example, the second information can indicate the resource pattern of the second resource (e.g., the resource pattern of the DMRS resource). Optionally, in this example, the second information can be physical layer signaling such as DCI, or the second information can be high layer signaling such as RRC signaling or MAC signaling, etc.

[0387] For example, the second information can include the seventh indication information described above. In this case, the resource pattern of the second resource can be predefined by the protocol, e.g., the resource pattern of the second resource includes the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4), and the 9th subcarrier (e.g., subcarrier 9) in a frequency-domain unit.

[0388] For example, the resource pattern of the second resource, such as the resource pattern of the DMRS of the control channel, can include at least one of FIG. 5b, FIG. 5c, or FIG. 5d.

[0389] Optionally, the seventh indication information can further indicate whether to perform rate matching by 1 bit. For example, bit 0 represents not performing rate matching, and bit 1 represents performing rate matching, or vice versa.

[0390] As another example, the first information can include the seventh indication information described above. The seventh indication information can indicate a first index corresponding to the resource pattern of the second resource, the first index being used to indicate one of the one or more resource patterns.

[0391] For example, the resource pattern corresponding to the resource pattern index w1 includes the 1st subcarrier (such as subcarrier 1), the 4th subcarrier (such as subcarrier 4), and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit. The seventh indication information can indicate the resource pattern index w1. Optionally, the resource pattern index w1 can correspond to one or more time domain units, for example, the resource pattern index w1 can correspond to one or more symbols, and the resource pattern of each symbol is the same as the resource pattern corresponding to the index w1.

[0392] For example, the resource pattern corresponding to the resource pattern index w2 includes the 1st subcarrier (such as subcarrier 1), the 4th subcarrier (such as subcarrier 4), and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit in one symbol. The seventh indication information can indicate the resource pattern index w2. As shown in the example of FIG. 5b, the RBs on each of the one or more symbols share 12 subcarriers, and the indexes of the subcarriers are subcarrier 0, 1, 2,..., 11. In FIG. 5b, the resource pattern of the control channel DMRS resource included in the second resource includes the 1st subcarrier (such as subcarrier 1), the 4th subcarrier (such as subcarrier 4), and the 9th subcarrier (such as subcarrier 9) in one frequency domain unit in one symbol.

[0393] For example, the resource pattern corresponding to the resource pattern index w3 includes the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4) and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on two symbols. The seventh indication information can indicate the resource pattern index w3. As shown in the example of FIG. 5c, the RBs on each of the one or more symbols share 12 subcarriers, which are indexed as subcarrier 0, 1, 2, …, 11. In FIG. 5c, the resource pattern of the control channel DMRS resource included in the second resource includes partial positions on two consecutive symbols (symbol indexes are 0 and 1, respectively), which include the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4) and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 0th symbol (e.g., symbol 0), and the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4) and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 1st symbol (e.g., symbol 1).

[0394] For example, the resource pattern corresponding to the resource pattern index w4 includes the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4) and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on three symbols. The seventh indication information can indicate the resource pattern index w4. As shown in the example of FIG. 5d, the RBs on each of the one or more symbols share 12 subcarriers, which are indexed as subcarrier 0, 1, 2, …, 11. In FIG. 5d, the resource pattern of the control channel DMRS resource included in the second resource includes partial positions on three consecutive symbols (symbol indexes are 0, 1 and 2, respectively), which include the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4) and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 0th symbol (e.g., symbol 0), the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4) and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 1st symbol (e.g., symbol 1), and the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4) and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the 2nd symbol (e.g., symbol 2).

[0395] As another example, the first information can include the seventh indication information described above. The seventh indication information is used to indicate the position of the resource unit included in the second resource in the frequency domain unit. For example, the seventh indication information is used to indicate that the resource pattern of the second resource includes the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4) and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit.

[0396] As another example, the first information can comprise the seventh indication information described in the foregoing. For example, the seventh indication information can indicate RE indices or RE positions.

[0397] For example, the second communication device indicates RE indices or RE positions (e.g., RE 1, 4, 9) to the first communication device through RRC signaling, and the fifth indication information can indicate the resource pattern through a bit map. For example, 1 RB includes 12 REs, a total of 12 bits, one bit representing one RE position, such as a bit map of 010010000100. The first bit represents RE 0, the second bit represents RE 1, and so on. A bit value of 0 represents that the resource pattern does not include the RE, and a bit value of 1 represents that the resource pattern includes the RE, and vice versa.

[0398] As another example, the first information can comprise the seventh indication information described in the foregoing. For example, the seventh indication information can indicate subcarrier indices or subcarrier positions.

[0399] For example, the second communication device indicates subcarrier indices or subcarrier positions (e.g., subcarrier 0, 4, 8) to the first communication device through RRC signaling, and the fifth indication information can indicate the resource pattern through a bit map. For example, 1 RB includes 12 subcarriers, a total of 12 bits, one bit representing one subcarrier position, such as a bit map of 010010000100. The first bit represents subcarrier 0, the second bit represents subcarrier 1, and so on. A bit value of 0 represents that the resource pattern does not include the subcarrier, and a bit value of 1 represents that the resource pattern includes the subcarrier, and vice versa.

[0400] As an example, the second information described above can be used to configure a resource pattern of a ZP CSI-RS resource or a resource pattern of a DMRS resource contained in the second resource, and the resource pattern of the ZP CSI-RS resource is the same as the resource pattern of the DMRS resource of the control channel.

[0401] Here, the resource pattern can be understood as an RE pattern (RE pattern), a subcarrier pattern, etc.

[0402] For example, the resource pattern of the ZP CSI-RS resource can include subcarrier 1, subcarrier 4, and subcarrier 9 in one frequency domain unit.

[0403] For example, the second information can indicate an RE pattern, so that the first communication device determines the position of the time-frequency resource which does not map data according to the CORESET configuration and the RE pattern.

[0404] Optionally, the second communication device can configure the CORESET and the RE pattern through high-layer signaling, i.e., the second information can be high-layer signaling.

[0405] Optionally, the second communication device can configure the CORESET through high layer signaling, and indicate the RE pattern without mapping data through physical layer signaling (i.e. the second information can be physical layer signaling). For example, the second communication device configures the CORESET through RRC signaling, and indicates the RE pattern without mapping data through DCI.

[0406] Optionally, the second communication device can configure the CORESET through high layer signaling (i.e. the second information can be high layer signaling), and configure the RE pattern without mapping data through high layer signaling.

[0407] For example, the second communication device configures the CORESET through RRC signaling, and configures the RE pattern without mapping data through MAC CE (i.e. the second information can be MAC CE).

[0408] As another example, the pattern of the control channel DMRS resource contained in the second resource is pre-configured or pre-defined.

[0409] As another example, the second information can include seventh indication information for configuring a resource pattern of a ZP CSI-RS resource or a resource pattern of the control channel DMRS resource contained in the second resource, the resource pattern of the ZP CSI-RS resource being the same as the resource pattern of the control channel DMRS resource. In other words, the pattern of the control channel DMRS resource contained in the second resource can be indicated through the ZP CSI-RS resource.

[0410] For example, the resource pattern of the ZP CSI-RS resource can include subcarriers 1, 4, 9 in one frequency domain unit.

[0411] As shown in the example of FIG. 5b, the RBs on each of the one or more symbols share 12 subcarriers, and the indexes of the subcarriers are subcarriers 0, 1, 2...11. In FIG. 5b, the resource pattern of the ZP CSI-RS resource contained in the second resource includes the 1st subcarrier (e.g. subcarrier 1), the 4th subcarrier (e.g. subcarrier 4) and the 9th subcarrier (e.g. subcarrier 9) in one frequency domain unit on one symbol.

[0412] As shown in the example of FIG. 5c, the RBs on each of the one or more symbols share 12 subcarriers, which are indexed as subcarriers 0, 1, 2, …, 11. In FIG. 5c, the resource pattern of the ZP CSI-RS resource included in the second resource includes partial positions on 2 consecutive symbols, including the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4), and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the first symbol, and the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4), and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the second symbol.

[0413] As shown in the example of FIG. 5d, the RBs on each of the one or more symbols share 12 subcarriers, which are indexed as subcarriers 0, 1, 2, …, 11. In FIG. 5d, the resource pattern of the ZP CSI-RS resource included in the second resource includes partial positions on 3 consecutive symbols, including the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4), and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the first symbol, the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4), and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the second symbol, and the 1st subcarrier (e.g., subcarrier 1), the 4th subcarrier (e.g., subcarrier 4), and the 9th subcarrier (e.g., subcarrier 9) in one frequency domain unit on the third symbol.

[0414] Optionally, the ith subcarrier in the present application can refer to the subcarrier i, or the subcarrier corresponding to the subcarrier number i.

[0415] As an example, the first information can include eighth indication information for configuring the time domain position of the DMRS resource included in the second resource. The eighth indication information can be implemented by at least one of the following multiple ways.

[0416] For example, the eighth indication information can indicate a first bit map for determining the symbol position of the second resource. For example, the second communication device sends DCI (i.e., the eighth indication information can be DCI) to the first communication device, and the DCI includes an indication of the symbol position.

[0417] Optionally, the symbol position can be indicated within a slot. For example, a slot includes x1 symbols, and the first bit map can indicate the symbol position by x1 bits. Wherein x1 is a positive integer. For example, a slot includes 14 symbols, and the bitmap is 14 bits. Alternatively,

[0418] Optionally, the symbol position can be indicated on the time domain resource of the first data channel. For example, if the time domain resource of the first data channel includes x2 symbols, the first bit bitmap can indicate the symbol position by x2 bits. Wherein, x2 is a positive integer. For example, if the first data channel occupies 6 symbols, the first bit bitmap can be 6 bits.

[0419] Optionally, the eighth indication information can indicate at least one of a starting time unit position, a time unit quantity, and a time domain density of the second resource. For example, the second communication device sends DCI to the first communication device, and the DCI includes an indication of a starting symbol position and / or a symbol length. For example, the second communication device indicates the starting symbol position and / or the symbol length in the second DCI.

[0420] Optionally, the starting symbol position indication is within a time slot. For example, if one time slot includes x3 symbols, the starting symbol position can be indicated by bits. Wherein, x3 is a positive integer. For example, if one time slot includes 14 symbols, 4 bits are needed to indicate the starting symbol position wherein, represents the upward rounding of log2 14.

[0421] Optionally, the starting symbol position can be indicated on the time domain resource of the first data channel. For example, if the time domain resource of the first data channel includes x4 symbols, the starting symbol position can be indicated by bits. Wherein, x4 is a positive integer, represents the upward rounding of log2 x4. For example, if the first data channel only occupies 6 symbols, 3 bits are needed to indicate the starting symbol position wherein, represents the upward rounding of log2 6.

[0422] Optionally, the symbol length can be 1, or 2, etc.

[0423] Optionally, the starting symbol position can be predefined, such as the starting symbol of a time slot, or the starting symbol of the first data channel, etc.

[0424] Optionally, the symbol length is predefined by a protocol, or configured by RRC signaling. For example, 1 or 2, etc.

[0425] Optionally, the eighth indication information can indicate a second bit bitmap. For example, the second communication device configures candidate symbol positions by RRC signaling, and indicates the second bit bitmap corresponding to the symbol position by DCI (i.e., the eighth indication information is DCI).

[0426] For example, the second communication device indicates candidate symbol positions, such as 4 positions, to the first communication device through RRC signaling. The symbol position bitmap can be indicated in the DCI, such as 4 bits. For example, the number of bits of the second bit map can be equal to the number of candidate symbol positions.

[0427] For example, the second communication device sends the DCI to the first communication device, and the symbol position bitmap is indicated in the DCI. For example, the second communication device indicates the symbol position bitmap in the second DCI. For example, the number of bits of the second bit map can be equal to the ceiling of log2(the number of candidate starting symbol positions).

[0428] For example, the eighth indication information can indicate a second index corresponding to a starting time unit position of the second resource, and the second index is used to indicate one of the one or more starting time unit positions. For example, the second communication device configures candidate starting symbol positions through RRC signaling, and indicates one of the starting symbol positions through the DCI (i.e., the eighth indication information is the DCI).

[0429] For example, the second communication device indicates candidate starting symbol positions, such as 4 positions, to the first communication device through RRC signaling. The starting symbol position can be indicated in the DCI, i.e., one of the 4 positions configured by the RRC signaling is indicated, such as through 2 bits of information.

[0430] For example, the second communication device sends the DCI to the first communication device, and the starting symbol position is indicated in the DCI. For example, the second communication device indicates the starting symbol position in the second DCI.

[0431] Optionally, the symbol length is pre-defined by the protocol, or configured by the RRC signaling. For example, 1 or 2, etc.

[0432] As an example, the first information can include ninth indication information for configuring the frequency domain position of the DMRS resource included in the second resource. The ninth indication information can be implemented by at least one of the following multiple ways.

[0433] As shown in the example of FIG. 5a, the frequency domain resource occupied by the first data channel can include 10 RBs in the figure, and the RE resource (i.e., the second resource) not mapped with data can be located on the 4 RBs with higher frequency domain positions.

[0434] For example, the ninth indication information can indicate at least one of the starting frequency domain unit position and / or the number of frequency domain units of the second resource. For example, the ninth indication information can be a DCI, and the second communication device sends the DCI to the first communication device, and the starting RB and the number of RBs are indicated in the DCI.

[0435] For example, the ninth indication information can indicate the position of the rate matched frequency domain resource in the frequency domain resource of the first data channel.

[0436] For example, the start frequency domain unit position is the position of the first data channel in the frequency domain resource, and the end frequency domain unit position is the position of the first data channel in the frequency domain resource.

[0437] As shown in the example of FIG. 5a, the start frequency domain unit position is the 5th frequency domain unit (such as frequency domain unit 5) in the frequency domain resource of the first data channel; the end frequency domain unit position is the 9th frequency domain unit (such as frequency domain unit 9) in the frequency domain resource of the first data channel; and the number of frequency domain units is 5 frequency domain units, such as frequency domain unit 5 to frequency domain unit 9.

[0438] For example, the ninth indication information can indicate the RBG index to which the second resource belongs. For example, the ninth indication information can be DCI, and the second communication device can send the DCI to the first communication device, and the DCI indicates the bit map of the RBG. Wherein, one RBG includes one or more RBs.

[0439] For example, the ninth indication information can indicate the position of the rate matched frequency domain resource in the frequency domain resource of the first data channel. For example, the frequency domain resource of the first data channel includes y1 RBGs, and the rate matched frequency domain resource can indicate the index of at least one RBG in the y1 RBGs.

[0440] Optionally, the index of the RBG can be the RBG index in the carrier or the bandwidth part (BWP), or the RBG index in the frequency domain resource of the first data channel.

[0441] For example, when the index of the RBG is the RBG index in the frequency domain resource of the first data channel, if the frequency domain resource of the first data channel includes y1 RBGs, the indicated rate matched RBG index can be from 0 to y1-1. For example, RBG index 0 represents the first RBG of the first data channel, RBG index 1 represents the second RBG of the first data channel, and so on, and RBG index y1-1 represents the y1th RBG of the first data channel.

[0442] For example, the ninth indication information can indicate a third index corresponding to a starting frequency domain unit position of the second resource, and the third index is used to indicate one of the one or more starting frequency domain unit positions. For example, the second communication device configures candidate starting RB positions through RRC signaling, and indicates one of the starting RB positions through DCI (i.e., the ninth indication information can be DCI). For example, the second communication device configures candidate starting RB positions through RRC signaling, such as 4 positions. The starting RB position is indicated in the second DCI, i.e., one of the 4 positions configured through RRC signaling is indicated, such as 2 bits.

[0443] Optionally, the RB length is pre-defined by a protocol or configured through RRC signaling.

[0444] For example, the ninth indication information can indicate a fourth index corresponding to a frequency domain unit quantity of the second resource, and the fourth index is used to indicate one of the one or more frequency domain unit quantities. For example, the second communication device configures candidate RB numbers as 4 types through RRC signaling, such as 4 RBs, 8 RBs, 16 RBs, and 32 RBs; and the second communication device sends DCI (i.e., the ninth indication information can be DCI) to the first communication device, and the DCI indicates the number of RBs, such as one of the 4 types configured through RRC signaling, such as 2 bits.

[0445] Optionally, the starting RB is pre-defined by a protocol, for example, the starting RB is the starting RB of the first data channel.

[0446] As described above, the second configuration information used to configure the second resource can include third information, and the third information is used to indicate a resource pattern of the RB-symbol level resource of the rate matching. The control channel DMRS resource included in the second resource is a resource in the resource pattern of the RB-symbol level resource.

[0447] For example, the third information can be RRC configuration information used to configure the rate matching resource, and the RRC configuration information includes a resource pattern of the RB-symbol level. For example, the RRC configuration information can indicate a bit map (e.g., RB bitmap) of the frequency domain resource and / or a bit map (e.g., Symbol bitmap) of the time domain resource. Optionally, the resource corresponding to the pattern of the PDCCH CCE or PDCCH DMRS in the RB-symbol in the pattern configured by the RRC configuration information needs to be rate matched.

[0448] Optionally, the rate matching resource configured by the RRC configuration information described above can be a periodic resource, a semi-persistent resource, or a non-periodic resource.

[0449] Optionally, the RRC configuration information can configure one or more resource identifiers for rate matching, and the dynamic rate matching is performed by activating one or more resource identifiers for rate matching in the DCI (i.e., the third information can include the RRC configuration information and the DCI).

[0450] In a third mode, the second resource can be a CCE resource and a control channel DMRS resource.

[0451] In the third mode, the second configuration information is used to configure the second resource, and the specific implementation of the second configuration information configuring the CCE resource can refer to the first mode described above, and the specific implementation of the second configuration information configuring the control channel DMRS resource can refer to the second mode described above, which will not be described here.

[0452] In a possible implementation of the method shown in FIG. 3, the method further includes that the first communication device receives third configuration information, the third configuration information being used to indicate at least one of resource pattern information, code division multiplexing group information, and sequence information of the DMRS of the first data channel. Specifically, the first communication device can further receive the third configuration information, so that the first communication device can determine at least one of the resource pattern information, the code division multiplexing group information, and the sequence information of the DMRS of the first data channel through the third configuration information, so as to receive the DMRS on the first data channel based on the at least one and demodulate / parse the data carried on the first data channel based on the received DMRS.

[0453] Optionally, the first configuration information and the third configuration information can be the same configuration information or different configuration information.

[0454] Optionally, the first configuration information and / or the third configuration information can be physical layer signaling such as DCI, or high layer signaling such as MAC signaling, or RRC signaling, etc.

[0455] In a possible implementation, at least one of the resource pattern information, the code division multiplexing group information, and the sequence information of the DMRS of the first data channel is determined based on a carrier where the first data channel is located. Specifically, the DMRS of the first data channel can be used to demodulate / parse the data carried on the first data channel, and the at least one of the resource pattern information, the code division multiplexing group information, and the sequence information of the DMRS of the first data channel can be determined based on the carrier where the first data channel is located. In this way, different carriers can have different DMRS configurations, and therefore the first communication device can perform the reception or transmission of the DMRS based on the DMRS configuration corresponding to the carrier where the data channel is located, so as to improve the reception / analysis success rate of the DMRS by the receiver of the DMRS, and further improve the data reception performance.

[0456] Optionally, the carrier where the first data channel is located can also be described as: the communication carrier where the first data channel is located.

[0457] As an example, in the case where the carrier where the first data channel is located is a communication carrier (for example, a shared carrier) of the first radio access technology and the second radio access technology, the communication device (for example, the first communication device, the second communication device, the third communication device described hereinafter, etc.) can determine that the communication carrier is used for communication of the first radio access technology and the second radio access technology at the same time. In this case, the communication device can determine at least one of the following:

[0458] The resource pattern information of the reference signal of the first radio access technology is the same as the resource pattern information of the reference signal of the second radio access technology; or, the code division multiplexing group information of the reference signal of the first radio access technology is the same as the code division multiplexing group information of the reference signal of the second radio access technology; or, the sequence information of the reference signal of the first radio access technology is the same as the sequence information of the reference signal of the second radio access technology.

[0459] In this way, on the shared carrier, different radio access technologies can use part of the same or all the same reference signal configuration, which can reduce the implementation complexity.

[0460] As another example, in the case where the carrier where the first data channel is located is a communication carrier (for example, a dedicated communication carrier) of the first radio access technology, the communication device (for example, the first communication device, the second communication device, the third communication device described hereinafter, etc.) can determine that the communication carrier is not used for communication of the second radio access technology. In this case, the communication device can determine at least one of the following:

[0461] The resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology; or, the code division multiplexing group information of the reference signal of the first radio access technology is different from the code division multiplexing group information of the reference signal of the second radio access technology; or, the sequence information of the reference signal of the first radio access technology is different from the sequence information of the reference signal of the second radio access technology.

[0462] In this way, on the dedicated carrier, different radio access technologies can use part of the different or all the different reference signal configurations, which can improve the flexibility of the scheme implementation and reduce the interference between the reference signals of different radio access technologies to improve the communication performance.

[0463] Optionally, the third configuration information and the carrier where the first data channel is located can be used to jointly determine at least one of the resource pattern information, the code division multiplexing group information, and the sequence information of the DMRS of the first data channel. For example, the carrier where the first data channel is located is used to determine at least one of one or more resource pattern information, one or more code division multiplexing group information, and one or more sequence information of the DMRS of the first data channel, and the third configuration information is used to indicate at least one of one of the one or more resource pattern information, one of the one or more code division multiplexing group information, or one of the one or more sequence information.

[0464] Optionally, the resource pattern information of the reference signal of the first radio access technology (i.e. the reference signal on the first data channel, such as DMRS) can be implemented in various ways.

[0465] As an example, the resource pattern information of the reference signal of the first radio access technology is the same as the resource pattern information of the reference signal of the second radio access technology; wherein the code division multiplexing group information of the reference signal of the first radio access technology is different from the code division multiplexing group information of the reference signal of the second radio access technology, and / or the sequence information of the reference signal of the first radio access technology is different from the sequence information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be the same, so that the reference signals of different radio access technologies can be distinguished by different code division multiplexing groups and / or different sequences (such as orthogonal sequences), to save resource overhead.

[0466] As another example, the resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology. In this way, the resource pattern information of the reference signals of different radio access technologies can be different, so that the reference signals of different radio access technologies can be distinguished by different resource patterns, to reduce implementation complexity.

[0467] For example, the third configuration information can indicate the resource pattern information of the reference signal of the first radio access technology by 1 bit.

[0468] For example, when the value of the 1 bit is “1”, it indicates that the resource pattern information of the reference signal of the first radio access technology is the same as the resource pattern information of the reference signal of the second radio access technology; and when the value of the 1 bit is “0”, it indicates that the resource pattern information of the reference signal of the first radio access technology is different from the resource pattern information of the reference signal of the second radio access technology.

[0469] For another example, when the 1 bit is set to "0", it indicates that the resource pattern information of the reference signal of the first radio access technology is the same as that of the reference signal of the second radio access technology; and when the 1 bit is set to "1", it indicates that the resource pattern information of the reference signal of the first radio access technology is different from that of the reference signal of the second radio access technology.

[0470] Similarly, the third configuration information can indicate the code division multiplexing group information of the reference signal of the first radio access technology by 1 bit.

[0471] For example, when the 1 bit is set to "1", it indicates that the code division multiplexing group information of the reference signal of the first radio access technology is the same as that of the reference signal of the second radio access technology; and when the 1 bit is set to "0", it indicates that the code division multiplexing group information of the reference signal of the first radio access technology is different from that of the reference signal of the second radio access technology.

[0472] For another example, when the 1 bit is set to "0", it indicates that the code division multiplexing group information of the reference signal of the first radio access technology is the same as that of the reference signal of the second radio access technology; and when the 1 bit is set to "1", it indicates that the code division multiplexing group information of the reference signal of the first radio access technology is different from that of the reference signal of the second radio access technology.

[0473] Similarly, the third configuration information can indicate the sequence information of the reference signal of the first radio access technology by 1 bit.

[0474] For example, when the 1 bit is set to "1", it indicates that the sequence information of the reference signal of the first radio access technology is the same as that of the reference signal of the second radio access technology; and when the 1 bit is set to "0", it indicates that the sequence information of the reference signal of the first radio access technology is different from that of the reference signal of the second radio access technology.

[0475] For another example, when the 1 bit is set to "0", it indicates that the sequence information of the reference signal of the first radio access technology is the same as that of the reference signal of the second radio access technology; and when the 1 bit is set to "1", it indicates that the sequence information of the reference signal of the first radio access technology is different from that of the reference signal of the second radio access technology.

[0476] As an example, taking the first radio access technology as 6G and the first data channel as 6G PDSCH (denoted as 6G PDSCH), and the second radio access technology as 5G as an example, the above implementation is exemplarily described in combination with some implementation examples.

[0477] For example, two patterns can be designed for 6G PDSCH DMRS, one pattern (such as pattern A) is used for 5G-6G shared carrier, such as using the design of 5G PDSCH DMRS, which can realize the spatial division multiplexing of 5G UE and 6G UE, the DMRS of 5G UE is orthogonal to the DMRS of 6G UE, and different CDM groups are used, and one pattern (such as pattern B) is used for 6G dedicated spectrum, such as sparse pilot, etc.

[0478] For example, two DMRS CDM groups can be designed for 6G PDSCH DMRS, one DMRS CDM group (such as CDM group A) is used for 5G-6G shared carrier, such as using the design of 5G PDSCH DMRS CDM group, which can realize the spatial division multiplexing of 5G UE and 6G UE, the DMRS of 5G UE is orthogonal to the DMRS of 6G UE, and different CDM groups are used, and one DMRS CDM group (such as CDM group B) is used for 6G dedicated spectrum, such as 6G CDM group, etc.

[0479] For example, two DMRS sequences can be designed for 6G PDSCH DMRS, one DMRS sequence (such as DMRS sequence A) is used for 5G-6G shared carrier, such as using the design of 5G PDSCH DMRS sequence, which can realize the spatial division multiplexing of 5G UE and 6G UE, the DMRS of 5G UE is orthogonal to the DMRS of 6G UE, and one DMRS sequence (such as DMRS sequence B) is used for 6G dedicated spectrum, such as 6G DMRS sequence, etc.

[0480] In the above examples, the third configuration information can be used to indicate the related information of 6G PDSCH DMRS, so that the first communication device determines the related information of 6G PDSCH DMRS according to the third configuration information.

[0481] For example, the related information of 6G PDSCH DMRS can include at least one of the pattern information of 6G DMRS, the information of 6G DMRS CDM group, and the information of 6G DMRS sequence.

[0482] For example, the related information of 6G PDSCH DMRS can be whether to use the related design of 5G DMRS.

[0483] Optionally, the third configuration information can be DCI, and 1 bit in the DCI can be used to indicate the related information of 6G PDSCH DMRS. For example, bit 0 represents pattern A, and bit 1 represents pattern B.

[0484] For example, bit 0 represents DMRS CDM group A, and bit 1 represents DMRS CDM group A.

[0485] For example, bit 0 represents DMRS sequence A, and bit 1 represents DMRS sequence B.

[0486] In a possible implementation of the method shown in FIG. 3, the method further includes that the first communication device receives fourth configuration information, the fourth configuration information being used to indicate that the TBS corresponding to the first data channel is determined based on the third resource. Specifically, the first communication device can further receive the fourth configuration information, so that the first communication device can determine, through the fourth configuration information, that the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, so as to enable the first communication device to implement the reception or transmission of the first data channel based on the TBS associated with the third resource, improve the accuracy of TBS calculation, and further improve the transmission performance of the first data channel.

[0487] Alternatively, the TBS corresponding to the first data channel is determined based on the third resource. Specifically, the first communication device can determine, through a preconfigured or predefined manner, that the TBS corresponding to the first data channel is determined based on the third resource excluding the second resource, so as to enable the first communication device to implement the reception or transmission of the first data channel based on the TBS associated with the third resource, and improve the reception performance of the receiver.

[0488] For example, in the case of PDSCH of NR, the flow of the communication device (for example, the first communication device, the second communication device, the third communication device described hereinafter, etc.) determining the TBS of the data channel can include:

[0489] Step 1: The communication device determines the number of REs of the PDSCH allocated in one RB, denoted as N' RE .

[0490] For example, N' RE satisfies:

[0491] wherein, represents the number of subcarriers of one RB in the frequency domain, is the number of OFDM symbols scheduled in one slot, represents the number of REs of DMRS in one PRB within the scheduling duration, including the overhead of the DMRS CDM group indicated in the DCI. The overhead value is configured through higher-level parameters (such as the parameter indicating overhead, Xoh-PDSCH). For example, the overhead value can be 0, 6, 12, or 18. If the higher-level parameter Xoh-PDSCH is not configured, the value of Xoh-PDSCH is 0.

[0492] Step 2, the communication device is based on N′ RE Determine the number of available REs N RE .

[0493] For example, N RE satisfy:

[0494] N RE =min(156, N′) RE )*n PRB ;

[0495] Where, n PRB This represents the total number of PRBs allocated to the communication device, min(156, N′). RE ) indicates taking 156 and N′ RE The minimum value in.

[0496] Optional, N RE Satisfy: N RE =N′ RE *n PRB .

[0497] Step 3, the communication device is based on N RE Determine the number of temporary information bits N info .

[0498] For example, N info Satisfy: N info =N RE *R*Q m *v;

[0499] Where R represents the code rate (e.g., determined by the modulation and coding scheme (MCS)), Q... m This indicates the adjustment method, and v indicates the number of layers (e.g., determined by the layer number indication information in DCI, or it can be predefined, such as 1 layer).

[0500] Step 4, the communication device is based on N info Determine TBS.

[0501] For example, in N info In the case of ≤3824, the communication device can determine the TBS based on a pre-configured or predefined table.

[0502] For example, in Ninfo In the case of 3824, the communication device can quantize the TBS to a multiple of 8. For example, after the TBS is cut into code blocks, if the number of code blocks cut according to the size of the code blocks is C, the final TBS needs to be a multiple of C*8. (If the code rate is less than 1 / 4, the size of the code block is 3840 (with a redundancy check code of 24 bits), otherwise the code block size is 8448 (with a redundancy check code of 24 bits)).

[0503] From the implementation process of steps 1 to 4, it can be seen that the determination process of the TBS takes into account the overhead of the DMRS of the first data channel (for example, the parameter ) and the overhead configured by the higher layer (for example, ). However, as described above, the first communication device receives or transmits the resources of the first data channel as the third resources, which do not include the second resources. Therefore, in the case of determining the TBS based on the above-mentioned steps 1 to 4, the calculation of the TBS will be inaccurate, which will affect the data transmission performance.

[0504] In the above technical solution, the TBS corresponding to the first data channel is determined based on the third resources, that is, the determination of the TBS takes into account the third resources which do not include the second resources, so that the determination process of the TBS also involves the overhead of the second resources (for example, the is replaced by: N″ RE represents the number of REs occupied by the second resources), which can improve the accurate calculation of the TBS, and further improve the data transmission performance to improve the communication performance.

[0505] Please refer to FIG. 6, which is another implementation schematic diagram of the communication method provided by the present application, and the method comprises the following steps.

[0506] S601. The second communication device transmits first configuration information, and correspondingly, the first communication device receives the first configuration information. The first configuration information is used to configure the first resources of the first data channel.

[0507] S602. The first communication device determines the TBS of the first data channel based on the third resources, wherein the third resources are included in the first resources, and the third resources do not include the second resources.

[0508] Optionally, the first communication device can communicate with other communication devices through the first data channel, and correspondingly, in the method shown in FIG. 6, the other communication devices determine the TBS of the first data channel based on the third resources.

[0509] For example, the other communication device is a second communication device, and the second communication device can communicate with the first communication device based on the TBS determined based on the third resources.

[0510] For example, the other communication device is a second communication device, and the second communication device can communicate with the first communication device based on the TBS determined based on the third resources.

[0511] Based on the scheme shown in FIG. 6, the first configuration information received by the first communication device in step S601 is used to configure the first resources of the first data channel, and the first communication device transmits or receives the first data channel on the third resources included in the first resources in step S602. The TBS corresponding to the first data channel is determined based on the third resources excluding the second resources, which can improve the accuracy of TBS calculation and further improve the transmission performance of the first data channel.

[0512] Optionally, after step S602, the first communication device can transmit or receive the first data channel on the third resources included in the first resources, so that the first communication device can implement the reception or transmission of the first data channel based on the TBS associated with the actually transmitted third resources, which can improve the transmission performance of the first data channel.

[0513] Optionally, any communication device (for example, the first communication device or the other communication device described above) determines the TBS of the first data channel based on the third resources, which can be understood as: the third resources are used to determine the TBS of the first data channel, or the TBS of the first data channel is determined based on the third resources.

[0514] Optionally, the TBS corresponding to the first data channel can also be referred to as the TBS of the first data channel.

[0515] In a possible implementation, the second resources are CCE resources and / or control channel DMRS resources. Specifically, the third resources of the first data channel transmitted by the first communication device do not include the CCE resources and / or DMRS resources on the control channel. Thus, the mutual influence and / or mutual interference between the transmission of the first data channel and the transmission of other signals on the second resources (i.e., control channel resources) can be avoided or reduced.

[0516] In a possible implementation, the method further includes: the first communication apparatus receiving fourth configuration information, the fourth configuration information being used to indicate that the TBS corresponding to the first data channel is determined based on the third resource. Specifically, the first communication apparatus can further receive the fourth configuration information, so that the first communication apparatus can determine, through the fourth configuration information, that the TBS corresponding to the first data channel is determined based on the third resource that does not include the second resource, so as to enable the first communication apparatus to implement the receiving or transmitting of the first data channel based on the TBS associated with the third resource, improve the accuracy of TBS calculation, and further improve the transmission performance of the first data channel.

[0517] Optionally, the first configuration information and the fourth configuration information can be the same configuration information or different configuration information.

[0518] Optionally, the first configuration information and / or the fourth configuration information can be physical layer signaling such as DCI, or high layer signaling such as MAC signaling, or RRC signaling, and the like.

[0519] It should be noted that in the method shown in FIG. 6, the implementation process of each step can refer to the description of FIG. 3 and related embodiments, and achieve the corresponding technical effects, which will not be repeated here.

[0520] Please refer to FIG. 7, the embodiment of the present application provides a communication apparatus 700, which can implement the functions of the first communication apparatus (or the second communication apparatus) in the above-mentioned method embodiments, and thus can also achieve the beneficial effects possessed by the above-mentioned method embodiments. In the embodiment of the present application, the communication apparatus 700 can be the first communication apparatus (or the second communication apparatus), or an integrated circuit or element inside the first communication apparatus (or the second communication apparatus), such as a chip, a baseband chip, a modem chip, a SoC chip (such as a SoC chip containing a modem core), a SIP chip, a communication module, a chip system, a processor, and the like.

[0521] It should be noted that the transceiver unit 702 can include a transmitting unit and a receiving unit, which are respectively used for performing transmitting and receiving.
